The smb.conf file is a configuration file for the Samba suite. smb.conf contains runtime configuration information for the Samba programs. The smb.conf file is designed to be configured and administered by the swat(8) program. The complete description of the file format and possible parameters held within are here for reference purposes.
The file consists of sections and parameters. A section begins with the name of the section in square brackets and continues until the next section begins. Sections contain parameters of the form
name = value
The file is line-based - that is, each newline-terminated line represents either a comment, a section name or a parameter.
Section and parameter names are not case sensitive.
Only the first equals sign in a parameter is significant. Whitespace before or after the first equals sign is discarded. Leading, trailing and internal whitespace in section and parameter names is irrelevant. Leading and trailing whitespace in a parameter value is discarded. Internal whitespace within a parameter value is retained verbatim.
Any line beginning with a semicolon (';') or a hash ('#') character is ignored, as are lines containing only whitespace.
Any line ending in a '\' is continued on the next line in the customary UNIX fashion.
The values following the equals sign in parameters are all either a string (no quotes needed) or a boolean, which may be given as yes/no, 0/1 or true/false. Case is not significant in boolean values, but is preserved in string values. Some items such as create modes are numeric.
Each section in the configuration file (except for the [global] section) describes a shared resource (known as a "share"). The section name is the name of the shared resource and the parameters within the section define the shares attributes.
There are three special sections, [global], [homes] and [printers], which are described under special sections. The following notes apply to ordinary section descriptions.
A share consists of a directory to which access is being given plus a description of the access rights which are granted to the user of the service. Some housekeeping options are also specifiable.
Sections are either file share services (used by the client as an extension of their native file systems) or printable services (used by the client to access print services on the host running the server).
Sections may be designated guest services, in which case no password is required to access them. A specified UNIX guest account is used to define access privileges in this case.
Sections other than guest services will require a password to access them. The client provides the username. As older clients only provide passwords and not usernames, you may specify a list of usernames to check against the password using the "user =" option in the share definition. For modern clients such as Windows 95/98/ME/NT/2000, this should not be necessary.
Note that the access rights granted by the server are masked by the access rights granted to the specified or guest UNIX user by the host system. The server does not grant more access than the host system grants.
The following sample section defines a file space share. The user has write access to the path /home/bar. The share is accessed via the share name "foo":
[foo] path = /home/bar writeable = true |
The following sample section defines a printable share. The share is readonly, but printable. That is, the only write access permitted is via calls to open, write to and close a spool file. The guest ok parameter means access will be permitted as the default guest user (specified elsewhere):
[aprinter] path = /usr/spool/public writeable = false printable = true guest ok = true |
parameters in this section apply to the server as a whole, or are defaults for sections which do not specifically define certain items. See the notes under PARAMETERS for more information.
If a section called homes is included in the configuration file, services connecting clients to their home directories can be created on the fly by the server.
When the connection request is made, the existing sections are scanned. If a match is found, it is used. If no match is found, the requested section name is treated as a user name and looked up in the local password file. If the name exists and the correct password has been given, a share is created by cloning the [homes] section.
Some modifications are then made to the newly created share:
The share name is changed from homes to the located username.
If no path was given, the path is set to the user's home directory.
If you decide to use a path = line in your [homes] section then you may find it useful to use the %S macro. For example :
path = /data/pchome/%S
would be useful if you have different home directories for your PCs than for UNIX access.
This is a fast and simple way to give a large number of clients access to their home directories with a minimum of fuss.
A similar process occurs if the requested section name is "homes", except that the share name is not changed to that of the requesting user. This method of using the [homes] section works well if different users share a client PC.
The [homes] section can specify all the parameters a normal service section can specify, though some make more sense than others. The following is a typical and suitable [homes] section:
[homes] writeable = yes |
An important point is that if guest access is specified in the [homes] section, all home directories will be visible to all clients without a password. In the very unlikely event that this is actually desirable, it would be wise to also specify read only access.
Note that the browseable flag for auto home directories will be inherited from the global browseable flag, not the [homes] browseable flag. This is useful as it means setting browseable = no in the [homes] section will hide the [homes] share but make any auto home directories visible.
This section works like [homes], but for printers.
If a [printers] section occurs in the configuration file, users are able to connect to any printer specified in the local host's printcap file.
When a connection request is made, the existing sections are scanned. If a match is found, it is used. If no match is found, but a [homes] section exists, it is used as described above. Otherwise, the requested section name is treated as a printer name and the appropriate printcap file is scanned to see if the requested section name is a valid printer share name. If a match is found, a new printer share is created by cloning the [printers] section.
A few modifications are then made to the newly created share:
The share name is set to the located printer name
If no printer name was given, the printer name is set to the located printer name
If the share does not permit guest access and no username was given, the username is set to the located printer name.
Note that the [printers] service MUST be printable - if you specify otherwise, the server will refuse to load the configuration file.
Typically the path specified would be that of a world-writeable spool directory with the sticky bit set on it. A typical [printers] entry would look like this:
[printers] path = /usr/spool/public guest ok = yes printable = yes |
All aliases given for a printer in the printcap file are legitimate printer names as far as the server is concerned. If your printing subsystem doesn't work like that, you will have to set up a pseudo-printcap. This is a file consisting of one or more lines like this:
alias|alias|alias|alias... |
Each alias should be an acceptable printer name for your printing subsystem. In the [global] section, specify the new file as your printcap. The server will then only recognize names found in your pseudo-printcap, which of course can contain whatever aliases you like. The same technique could be used simply to limit access to a subset of your local printers.
An alias, by the way, is defined as any component of the first entry of a printcap record. Records are separated by newlines, components (if there are more than one) are separated by vertical bar symbols ('|').
NOTE: On SYSV systems which use lpstat to determine what printers are defined on the system you may be able to use "printcap name = lpstat" to automatically obtain a list of printers. See the "printcap name" option for more details.
parameters define the specific attributes of sections.
Some parameters are specific to the [global] section (e.g., security). Some parameters are usable in all sections (e.g., create mode). All others are permissible only in normal sections. For the purposes of the following descriptions the [homes] and [printers] sections will be considered normal. The letter G in parentheses indicates that a parameter is specific to the [global] section. The letter S indicates that a parameter can be specified in a service specific section. Note that all S parameters can also be specified in the [global] section - in which case they will define the default behavior for all services.
parameters are arranged here in alphabetical order - this may not create best bedfellows, but at least you can find them! Where there are synonyms, the preferred synonym is described, others refer to the preferred synonym.
Many of the strings that are settable in the config file can take substitutions. For example the option "path = /tmp/%u" would be interpreted as "path = /tmp/john" if the user connected with the username john.
These substitutions are mostly noted in the descriptions below, but there are some general substitutions which apply whenever they might be relevant. These are:
the name of the current service, if any.
the root directory of the current service, if any.
user name of the current service, if any.
primary group name of %u.
session user name (the user name that the client wanted, not necessarily the same as the one they got).
primary group name of %U.
the home directory of the user given by %u.
the Samba version.
the Internet hostname that Samba is running on.
the NetBIOS name of the client machine (very useful).
the NetBIOS name of the server. This allows you to change your config based on what the client calls you. Your server can have a "dual personality".
the Internet name of the client machine.
the name of your NIS home directory server. This is obtained from your NIS auto.map entry. If you have not compiled Samba with the --with-automount option then this value will be the same as %L.
the path of the service's home directory, obtained from your NIS auto.map entry. The NIS auto.map entry is split up as "%N:%p".
the selected protocol level after protocol negotiation. It can be one of CORE, COREPLUS, LANMAN1, LANMAN2 or NT1.
The process id of the current server process.
the architecture of the remote machine. Only some are recognized, and those may not be 100% reliable. It currently recognizes Samba, WfWg, WinNT and Win95. Anything else will be known as "UNKNOWN". If it gets it wrong then sending a level 3 log to samba@samba.org should allow it to be fixed.
The IP address of the client machine.
the current date and time.
The value of the environment variable envar.
There are some quite creative things that can be done with these substitutions and other smb.conf options.
Samba supports "name mangling" so that DOS and Windows clients can use files that don't conform to the 8.3 format. It can also be set to adjust the case of 8.3 format filenames.
There are several options that control the way mangling is performed, and they are grouped here rather than listed separately. For the defaults look at the output of the testparm program.
All of these options can be set separately for each service (or globally, of course).
The options are:
controls if names that have characters that aren't of the "default" case are mangled. For example, if this is yes then a name like "Mail" would be mangled. Default no.
controls whether filenames are case sensitive. If they aren't then Samba must do a filename search and match on passed names. Default no.
controls what the default case is for new filenames. Default lower.
controls if new files are created with the case that the client passes, or if they are forced to be the "default" case. Default yes.
controls if new files which conform to 8.3 syntax, that is all in upper case and of suitable length, are created upper case, or if they are forced to be the "default" case. This option can be use with "preserve case = yes" to permit long filenames to retain their case, while short names are lowered. Default yes.
By default, Samba 2.2 has the same semantics as a Windows NT server, in that it is case insensitive but case preserving.
There are a number of ways in which a user can connect to a service. The server uses the following steps in determining if it will allow a connection to a specified service. If all the steps fail, then the connection request is rejected. However, if one of the steps succeeds, then the following steps are not checked.
If the service is marked "guest only = yes" then steps 1 to 5 are skipped.
If the client has passed a username/password pair and that username/password pair is validated by the UNIX system's password programs then the connection is made as that username. Note that this includes the \\server\service%username method of passing a username.
If the client has previously registered a username with the system and now supplies a correct password for that username then the connection is allowed.
The client's netbios name and any previously used user names are checked against the supplied password, if they match then the connection is allowed as the corresponding user.
If the client has previously validated a username/password pair with the server and the client has passed the validation token then that username is used.
If a "user = " field is given in the smb.conf file for the service and the client has supplied a password, and that password matches (according to the UNIX system's password checking) with one of the usernames from the "user =" field then the connection is made as the username in the "user =" line. If one of the username in the "user =" list begins with a '@' then that name expands to a list of names in the group of the same name.
If the service is a guest service then a connection is made as the username given in the "guest account =" for the service, irrespective of the supplied password.
Here is a list of all global parameters. See the section of each parameter for details. Note that some are synonyms.
Here is a list of all service parameters. See the section on each parameter for details. Note that some are synonyms.
With the introduction of MS-RPC based printing support for Windows NT/2000 clients in Samba 2.2, The MS Add Printer Wizard (APW) icon is now also available in the "Printers..." folder displayed a share listing. The APW allows for printers to be add remotely to a Samba or Windows NT/2000 print server.
For a Samba host this means that the printer must be physically added to underlying printing system. The add printer command defines a script to be run which will perform the necessary operations for adding the printer to the print system and to add the appropriate service definition to the smb.conf file in order that it can be shared by smbd(8) .
The add printer command is automatically invoked with the following parameter (in order:
printer name
share name
port name
driver name
location
Windows 9x driver location
All parameters are filled in from the PRINTER_INFO_2 structure sent by the Windows NT/2000 client with one exception. The "Windows 9x driver location" parameter is included for backwards compatibility only. The remaining fields in the structure are generated from answers to the APW questions.
Once the add printer command has been executed, smbd will reparse the smb.conf to determine if the share defined by the APW exists. If the sharename is still invalid, then smbd will return an ACCESS_DENIED error to the client.
See also delete printer command, printing, show add printer wizard
Default: none
Example: addprinter command = /usr/bin/addprinter
Samba 2.2.0 introduced the ability to dynamically add and delete shares via the Windows NT 4.0 Server Manager. The add share command is used to define an external program or script which will add a new service definition to smb.conf. In order to successfully execute the add share command, smbd requires that the administrator be connected using a root account (i.e. uid == 0).
When executed, smbd will automatically invoke the add share command with four parameters.
configFile - the location of the global smb.conf file.
shareName - the name of the new share.
pathName - path to an **existing** directory on disk.
comment - comment string to associate with the new share.
This parameter is only used for add file shares. To add printer shares, see the add printer command.
See also change share command, delete share command.
Default: none
Example: add share command = /usr/local/bin/addshare
This is the full pathname to a script that will be run AS ROOT by smbd(8) under special circumstances described below.
Normally, a Samba server requires that UNIX users are created for all users accessing files on this server. For sites that use Windows NT account databases as their primary user database creating these users and keeping the user list in sync with the Windows NT PDC is an onerous task. This option allows smbd to create the required UNIX users ON DEMAND when a user accesses the Samba server.
In order to use this option, smbd must be set to security = server or security = domain and add user script must be set to a full pathname for a script that will create a UNIX user given one argument of %u, which expands into the UNIX user name to create.
When the Windows user attempts to access the Samba server, at login (session setup in the SMB protocol) time, smbd contacts the password server and attempts to authenticate the given user with the given password. If the authentication succeeds then smbd attempts to find a UNIX user in the UNIX password database to map the Windows user into. If this lookup fails, and add user script is set then smbd will call the specified script AS ROOT, expanding any %u argument to be the user name to create.
If this script successfully creates the user then smbd will continue on as though the UNIX user already existed. In this way, UNIX users are dynamically created to match existing Windows NT accounts.
See also security, password server, delete user script.
Default: add user script = <empty string>
Example: add user script = /usr/local/samba/bin/add_user %u
This is a list of users who will be granted administrative privileges on the share. This means that they will do all file operations as the super-user (root).
You should use this option very carefully, as any user in this list will be able to do anything they like on the share, irrespective of file permissions.
Default: no admin users
Example: admin users = jason
Synonym for hosts allow.
This option only takes effect when the security option is set to server or domain. If it is set to no, then attempts to connect to a resource from a domain or workgroup other than the one which smbd is running in will fail, even if that domain is trusted by the remote server doing the authentication.
This is useful if you only want your Samba server to serve resources to users in the domain it is a member of. As an example, suppose that there are two domains DOMA and DOMB. DOMB is trusted by DOMA, which contains the Samba server. Under normal circumstances, a user with an account in DOMB can then access the resources of a UNIX account with the same account name on the Samba server even if they do not have an account in DOMA. This can make implementing a security boundary difficult.
Default: allow trusted domains = yes
This specifies what type of server nmbd will announce itself as, to a network neighborhood browse list. By default this is set to Windows NT. The valid options are : "NT Server" (which can also be written as "NT"), "NT Workstation", "Win95" or "WfW" meaning Windows NT Server, Windows NT Workstation, Windows 95 and Windows for Workgroups respectively. Do not change this parameter unless you have a specific need to stop Samba appearing as an NT server as this may prevent Samba servers from participating as browser servers correctly.
Default: announce as = NT Server
Example: announce as = Win95
This specifies the major and minor version numbers that nmbd will use when announcing itself as a server. The default is 4.2. Do not change this parameter unless you have a specific need to set a Samba server to be a downlevel server.
Default: announce version = 4.2
Example: announce version = 2.0
This is a synonym for the preload.
This parameter lets you "turn off" a service. If available = no, then ALL attempts to connect to the service will fail. Such failures are logged.
Default: available = yes
This global parameter allows the Samba admin to limit what interfaces on a machine will serve smb requests. If affects file service smbd(8) and name service nmbd(8) in slightly different ways.
For name service it causes nmbd to bind to ports 137 and 138 on the interfaces listed in the interfaces parameter. nmbd also binds to the "all addresses" interface (0.0.0.0) on ports 137 and 138 for the purposes of reading broadcast messages. If this option is not set then nmbd will service name requests on all of these sockets. If bind interfaces only is set then nmbd will check the source address of any packets coming in on the broadcast sockets and discard any that don't match the broadcast addresses of the interfaces in the interfaces parameter list. As unicast packets are received on the other sockets it allows nmbd to refuse to serve names to machines that send packets that arrive through any interfaces not listed in the interfaces list. IP Source address spoofing does defeat this simple check, however so it must not be used seriously as a security feature for nmbd.
For file service it causes smbd(8) to bind only to the interface list given in the interfaces parameter. This restricts the networks that smbd will serve to packets coming in those interfaces. Note that you should not use this parameter for machines that are serving PPP or other intermittent or non-broadcast network interfaces as it will not cope with non-permanent interfaces.
If bind interfaces only is set then unless the network address 127.0.0.1 is added to the interfaces parameter list smbpasswd(8) and swat(8) may not work as expected due to the reasons covered below.
To change a users SMB password, the smbpasswd by default connects to the localhost - 127.0.0.1 address as an SMB client to issue the password change request. If bind interfaces only is set then unless the network address 127.0.0.1 is added to the interfaces parameter list then smbpasswd will fail to connect in it's default mode. smbpasswd can be forced to use the primary IP interface of the local host by using its -r remote machine parameter, with remote machine set to the IP name of the primary interface of the local host.
The swat status page tries to connect with smbd and nmbd at the address 127.0.0.1 to determine if they are running. Not adding 127.0.0.1 will cause smbd and nmbd to always show "not running" even if they really are. This can prevent swat from starting/stopping/restarting smbd and nmbd.
Default: bind interfaces only = no
This parameter controls the behavior of smbd(8) when given a request by a client to obtain a byte range lock on a region of an open file, and the request has a time limit associated with it.
If this parameter is set and the lock range requested cannot be immediately satisfied, Samba 2.2 will internally queue the lock request, and periodically attempt to obtain the lock until the timeout period expires.
If this parameter is set to False, then Samba 2.2 will behave as previous versions of Samba would and will fail the lock request immediately if the lock range cannot be obtained.
Default: blocking locks = yes
See the browseable.
This controls whether smbd(8) will serve a browse list to a client doing a NetServerEnum call. Normally set to true. You should never need to change this.
Default: browse list = yes
This controls whether this share is seen in the list of available shares in a net view and in the browse list.
Default: browseable = yes
See the discussion in the section NAME MANGLING.
Default: case sensitive = no
Synonym for case sensitive.
This SMB allows a client to tell a server to "watch" a particular directory for any changes and only reply to the SMB request when a change has occurred. Such constant scanning of a directory is expensive under UNIX, hence an smbd(8) daemon only performs such a scan on each requested directory once every change notify timeout seconds.
Default: change notify timeout = 60
Example: change notify timeout = 300
Would change the scan time to every 5 minutes.
Samba 2.2.0 introduced the ability to dynamically add and delete shares via the Windows NT 4.0 Server Manager. The change share command is used to define an external program or script which will modify an existing service definition in smb.conf. In order to successfully execute the change share command, smbd requires that the administrator be connected using a root account (i.e. uid == 0).
When executed, smbd will automatically invoke the change share command with four parameters.
configFile - the location of the global smb.conf file.
shareName - the name of the new share.
pathName - path to an **existing** directory on disk.
comment - comment string to associate with the new share.
This parameter is only used modify existing file shares definitions. To modify printer shares, use the "Printers..." folder as seen when browsing the Samba host.
See also add share command, delete share command.
Default: none
Example: change share command = /usr/local/bin/addshare
This allows a smbd to map incoming filenames from a DOS Code page (see the client code page parameter) to several built in UNIX character sets. The built in code page translations are:
ISO8859-1 : Western European UNIX character set. The parameter client code page MUST be set to code page 850 if the character set parameter is set to ISO8859-1 in order for the conversion to the UNIX character set to be done correctly.
ISO8859-2 : Eastern European UNIX character set. The parameter client code page MUST be set to code page 852 if the character set parameter is set to ISO8859-2 in order for the conversion to the UNIX character set to be done correctly.
ISO8859-5 : Russian Cyrillic UNIX character set. The parameter client code page MUST be set to code page 866 if the character set parameter is set to ISO8859-5 in order for the conversion to the UNIX character set to be done correctly.
ISO8859-7 : Greek UNIX character set. The parameter client code page MUST be set to code page 737 if the character set parameter is set to ISO8859-7 in order for the conversion to the UNIX character set to be done correctly.
KOI8-R : Alternate mapping for Russian Cyrillic UNIX character set. The parameter client code page MUST be set to code page 866 if the character set parameter is set to KOI8-R in order for the conversion to the UNIX character set to be done correctly.
BUG. These MSDOS code page to UNIX character set mappings should be dynamic, like the loading of MS DOS code pages, not static.
Normally this parameter is not set, meaning no filename translation is done.
Default: character set = <empty string>
Example: character set = ISO8859-1
This parameter specifies the DOS code page that the clients accessing Samba are using. To determine what code page a Windows or DOS client is using, open a DOS command prompt and type the command chcp. This will output the code page. The default for USA MS-DOS, Windows 95, and Windows NT releases is code page 437. The default for western European releases of the above operating systems is code page 850.
This parameter tells smbd(8) which of the codepage.XXX files to dynamically load on startup. These files, described more fully in the manual page make_smbcodepage(1), tell smbd how to map lower to upper case characters to provide the case insensitivity of filenames that Windows clients expect.
Samba currently ships with the following code page files :
Code Page 437 - MS-DOS Latin US
Code Page 737 - Windows '95 Greek
Code Page 850 - MS-DOS Latin 1
Code Page 852 - MS-DOS Latin 2
Code Page 861 - MS-DOS Icelandic
Code Page 866 - MS-DOS Cyrillic
Code Page 932 - MS-DOS Japanese SJIS
Code Page 936 - MS-DOS Simplified Chinese
Code Page 949 - MS-DOS Korean Hangul
Code Page 950 - MS-DOS Traditional Chinese
Thus this parameter may have any of the values 437, 737, 850, 852, 861, 932, 936, 949, or 950. If you don't find the codepage you need, read the comments in one of the other codepage files and the make_smbcodepage(1) man page and write one. Please remember to donate it back to the Samba user community.
This parameter co-operates with the valid chars parameter in determining what characters are valid in filenames and how capitalization is done. If you set both this parameter and the valid chars parameter the client code page parameter MUST be set before the valid chars parameter in the smb.conf file. The valid chars string will then augment the character settings in the client code page parameter.
If not set, client code page defaults to 850.
See also : valid chars, code page directory
Default: client code page = 850
Example: client code page = 936
Define the location of the various client code page files.
See also client code page
Default: code page directory = ${prefix}/lib/codepages
Example: code page directory = /usr/share/samba/codepages
This parameter is used to determine how incoming Shift-JIS Japanese characters are mapped from the incoming client code page used by the client, into file names in the UNIX filesystem. Only useful if client code page is set to 932 (Japanese Shift-JIS). The options are :
SJIS - Shift-JIS. Does no conversion of the incoming filename.
JIS8, J8BB, J8BH, J8@B, J8@J, J8@H - Convert from incoming Shift-JIS to eight bit JIS code with different shift-in, shift out codes.
JIS7, J7BB, J7BH, J7@B, J7@J, J7@H - Convert from incoming Shift-JIS to seven bit JIS code with different shift-in, shift out codes.
JUNET, JUBB, JUBH, JU@B, JU@J, JU@H - Convert from incoming Shift-JIS to JUNET code with different shift-in, shift out codes.
EUC - Convert an incoming Shift-JIS character to EUC code.
HEX - Convert an incoming Shift-JIS character to a 3 byte hex representation, i.e. :AB.
CAP - Convert an incoming Shift-JIS character to the 3 byte hex representation used by the Columbia AppleTalk Program (CAP), i.e. :AB. This is used for compatibility between Samba and CAP.
Default: coding system = <empty value>
This is a text field that is seen next to a share when a client does a queries the server, either via the network neighborhood or via net view to list what shares are available.
If you want to set the string that is displayed next to the machine name then see the server string parameter.
Default: No comment string
Example: comment = Fred's Files
This allows you to override the config file to use, instead of the default (usually smb.conf). There is a chicken and egg problem here as this option is set in the config file!
For this reason, if the name of the config file has changed when the parameters are loaded then it will reload them from the new config file.
This option takes the usual substitutions, which can be very useful.
If the config file doesn't exist then it won't be loaded (allowing you to special case the config files of just a few clients).
Example: config file = /usr/local/samba/lib/smb.conf.%m
This parameter allows you to "clone" service entries. The specified service is simply duplicated under the current service's name. Any parameters specified in the current section will override those in the section being copied.
This feature lets you set up a 'template' service and create similar services easily. Note that the service being copied must occur earlier in the configuration file than the service doing the copying.
Default: no value
Example: copy = otherservice
A synonym for this parameter is create mode .
When a file is created, the necessary permissions are calculated according to the mapping from DOS modes to UNIX permissions, and the resulting UNIX mode is then bit-wise 'AND'ed with this parameter. This parameter may be thought of as a bit-wise MASK for the UNIX modes of a file. Any bit not set here will be removed from the modes set on a file when it is created.
The default value of this parameter removes the 'group' and 'other' write and execute bits from the UNIX modes.
Following this Samba will bit-wise 'OR' the UNIX mode created from this parameter with the value of the force create mode parameter which is set to 000 by default.
This parameter does not affect directory modes. See the parameter directory mode for details.
See also the force create mode parameter for forcing particular mode bits to be set on created files. See also the directory mode parameter for masking mode bits on created directories. See also the inherit permissions parameter.
Note that this parameter does not apply to permissions set by Windows NT/2000 ACL editors. If the administrator wishes to enforce a mask on access control lists also, they need to set the security mask.
Default: create mask = 0744
Example: create mask = 0775
This is a synonym for create mask.
The value of the parameter (a decimal integer) represents the number of minutes of inactivity before a connection is considered dead, and it is disconnected. The deadtime only takes effect if the number of open files is zero.
This is useful to stop a server's resources being exhausted by a large number of inactive connections.
Most clients have an auto-reconnect feature when a connection is broken so in most cases this parameter should be transparent to users.
Using this parameter with a timeout of a few minutes is recommended for most systems.
A deadtime of zero indicates that no auto-disconnection should be performed.
Default: deadtime = 0
Example: deadtime = 15
Sometimes the timestamps in the log messages are needed with a resolution of higher that seconds, this boolean parameter adds microsecond resolution to the timestamp message header when turned on.
Note that the parameter debug timestamp must be on for this to have an effect.
Default: debug hires timestamp = no
When using only one log file for more then one forked smbd-process there may be hard to follow which process outputs which message. This boolean parameter is adds the process-id to the timestamp message headers in the logfile when turned on.
Note that the parameter debug timestamp must be on for this to have an effect.
Default: debug pid = no
Samba 2.2 debug log messages are timestamped by default. If you are running at a high debug level these timestamps can be distracting. This boolean parameter allows timestamping to be turned off.
Default: debug timestamp = yes
Samba is sometimes run as root and sometime run as the connected user, this boolean parameter inserts the current euid, egid, uid and gid to the timestamp message headers in the log file if turned on.
Note that the parameter debug timestamp must be on for this to have an effect.
Default: debug uid = no
Synonym for log level.
A synonym for default service.
See the section on NAME MANGLING. Also note the short preserve case parameter.
Default: default case = lower
This parameter specifies the name of a service which will be connected to if the service actually requested cannot be found. Note that the square brackets are NOT given in the parameter value (see example below).
There is no default value for this parameter. If this parameter is not given, attempting to connect to a nonexistent service results in an error.
Typically the default service would be a guest ok, read-only service.
Also note that the apparent service name will be changed to equal that of the requested service, this is very useful as it allows you to use macros like %S to make a wildcard service.
Note also that any "_" characters in the name of the service used in the default service will get mapped to a "/". This allows for interesting things.
Example:
[global]
default service = pub
[pub]
path = /%S

With the introduction of MS-RPC based printer support for Windows NT/2000 clients in Samba 2.2, it is now possible to delete printer at run time by issuing the DeletePrinter() RPC call.
For a Samba host this means that the printer must be physically deleted from underlying printing system. The deleteprinter command defines a script to be run which will perform the necessary operations for removing the printer from the print system and from smb.conf.
The delete printer command is automatically called with only one parameter: "printer name".
Once the delete printer command has been executed, smbd will reparse the smb.conf to associated printer no longer exists. If the sharename is still valid, then smbd will return an ACCESS_DENIED error to the client.
See also add printer command, printing, show add printer wizard
Default: none
Example: deleteprinter command = /usr/bin/removeprinter
This parameter allows readonly files to be deleted. This is not normal DOS semantics, but is allowed by UNIX.
This option may be useful for running applications such as rcs, where UNIX file ownership prevents changing file permissions, and DOS semantics prevent deletion of a read only file.
Default: delete readonly = no
Samba 2.2.0 introduced the ability to dynamically add and delete shares via the Windows NT 4.0 Server Manager. The delete share command is used to define an external program or script which will remove an existing service definition from smb.conf. In order to successfully execute the delete share command, smbd requires that the administrator be connected using a root account (i.e. uid == 0).
When executed, smbd will automatically invoke the delete share command with two parameters.
configFile - the location of the global smb.conf file.
shareName - the name of the existing service.
This parameter is only used to remove file shares. To delete printer shares, see the delete printer command.
See also delete share command, change share.
Default: none
Example: delete share command = /usr/local/bin/delshare
This is the full pathname to a script that will be run AS ROOT by smbd(8) under special circumstances described below.
Normally, a Samba server requires that UNIX users are created for all users accessing files on this server. For sites that use Windows NT account databases as their primary user database creating these users and keeping the user list in sync with the Windows NT PDC is an onerous task. This option allows smbd to delete the required UNIX users ON DEMAND when a user accesses the Samba server and the Windows NT user no longer exists.
In order to use this option, smbd must be set to security = domain and delete user script must be set to a full pathname for a script that will delete a UNIX user given one argument of %u , which expands into the UNIX user name to delete. NOTE that this is different to the add user script which will work with the security = server option as well as security = domain. The reason for this is only when Samba is a domain member does it get the information on an attempted user logon that a user no longer exists. In the security = server mode a missing user is treated the same as an invalid password logon attempt. Deleting the user in this circumstance would not be a good idea.
When the Windows user attempts to access the Samba server, at login (session setup in the SMB protocol) time, smbd contacts the password server and attempts to authenticate the given user with the given password. If the authentication fails with the specific Domain error code meaning that the user no longer exists then smbd attempts to find a UNIX user in the UNIX password database that matches the Windows user account. If this lookup succeeds, and delete user script is set then smbd will all the specified script AS ROOT, expanding any %u argument to be the user name to delete.
This script should delete the given UNIX username. In this way, UNIX users are dynamically deleted to match existing Windows NT accounts.
See also security = domain, password server , add user script .
Default: delete user script = <empty string>
Example: delete user script = /usr/local/samba/bin/del_user %u
This option is used when Samba is attempting to delete a directory that contains one or more vetoed directories (see the veto files option). If this option is set to False (the default) then if a vetoed directory contains any non-vetoed files or directories then the directory delete will fail. This is usually what you want.
If this option is set to True, then Samba will attempt to recursively delete any files and directories within the vetoed directory. This can be useful for integration with file serving systems such as NetAtalk which create meta-files within directories you might normally veto DOS/Windows users from seeing (e.g. .AppleDouble)
Setting delete veto files = yes allows these directories to be transparently deleted when the parent directory is deleted (so long as the user has permissions to do so).
See also the veto files parameter.
Default: delete veto files = no
Synonym for hosts deny.
The dfree command setting should only be used on systems where a problem occurs with the internal disk space calculations. This has been known to happen with Ultrix, but may occur with other operating systems. The symptom that was seen was an error of "Abort Retry Ignore" at the end of each directory listing.
This setting allows the replacement of the internal routines to calculate the total disk space and amount available with an external routine. The example below gives a possible script that might fulfill this function.
The external program will be passed a single parameter indicating a directory in the filesystem being queried. This will typically consist of the string ./. The script should return two integers in ASCII. The first should be the total disk space in blocks, and the second should be the number of available blocks. An optional third return value can give the block size in bytes. The default blocksize is 1024 bytes.
Note: Your script should NOT be setuid or setgid and should be owned by (and writeable only by) root!
Default: By default internal routines for determining the disk capacity and remaining space will be used.
Example: dfree command = /usr/local/samba/bin/dfree
Where the script dfree (which must be made executable) could be:
#!/bin/sh
df $1 | tail -1 | awk '{print $2" "$4}'
|
or perhaps (on Sys V based systems):
#!/bin/sh
/usr/bin/df -k $1 | tail -1 | awk '{print $3" "$5}'
|
Note that you may have to replace the command names with full path names on some systems.
Synonym for path .
This parameter is the octal modes which are used when converting DOS modes to UNIX modes when creating UNIX directories.
When a directory is created, the necessary permissions are calculated according to the mapping from DOS modes to UNIX permissions, and the resulting UNIX mode is then bit-wise 'AND'ed with this parameter. This parameter may be thought of as a bit-wise MASK for the UNIX modes of a directory. Any bit not set here will be removed from the modes set on a directory when it is created.
The default value of this parameter removes the 'group' and 'other' write bits from the UNIX mode, allowing only the user who owns the directory to modify it.
Following this Samba will bit-wise 'OR' the UNIX mode created from this parameter with the value of the force directory mode parameter. This parameter is set to 000 by default (i.e. no extra mode bits are added).
Note that this parameter does not apply to permissions set by Windows NT/2000 ACL editors. If the administrator wishes to enforce a mask on access control lists also, they need to set the directory security mask.
See the force directory mode parameter to cause particular mode bits to always be set on created directories.
See also the create mode parameter for masking mode bits on created files, and the directory security mask parameter.
Also refer to the inherit permissions parameter.
Default: directory mask = 0755
Example: directory mask = 0775
Synonym for directory mask
This parameter controls what UNIX permission bits can be modified when a Windows NT client is manipulating the UNIX permission on a directory using the native NT security dialog box.
This parameter is applied as a mask (AND'ed with) to the changed permission bits, thus preventing any bits not in this mask from being modified. Essentially, zero bits in this mask may be treated as a set of bits the user is not allowed to change.
If not set explicitly this parameter is set to 0777 meaning a user is allowed to modify all the user/group/world permissions on a directory.
Note that users who can access the Samba server through other means can easily bypass this restriction, so it is primarily useful for standalone "appliance" systems. Administrators of most normal systems will probably want to leave it as the default of 0777.
See also the force directory security mode, security mask, force security mode parameters.
Default: directory security mask = 0777
Example: directory security mask = 0700
Specifies that nmbd(8) when acting as a WINS server and finding that a NetBIOS name has not been registered, should treat the NetBIOS name word-for-word as a DNS name and do a lookup with the DNS server for that name on behalf of the name-querying client.
Note that the maximum length for a NetBIOS name is 15 characters, so the DNS name (or DNS alias) can likewise only be 15 characters, maximum.
nmbd spawns a second copy of itself to do the DNS name lookup requests, as doing a name lookup is a blocking action.
See also the parameter wins support.
Default: dns proxy = yes
This parameter is intended as a temporary solution to enable users to be a member of the "Domain Admins" group when a Samba host is acting as a PDC. A complete solution will be provided by a system for mapping Windows NT/2000 groups onto UNIX groups. Please note that this parameter has a somewhat confusing name. It accepts a list of usernames and of group names in standard smb.conf notation.
See also domain guest group, domain logons
Default: no domain administrators
Example: domain admin group = root @wheel
This parameter is intended as a temporary solution to enable users to be a member of the "Domain Guests" group when a Samba host is acting as a PDC. A complete solution will be provided by a system for mapping Windows NT/2000 groups onto UNIX groups. Please note that this parameter has a somewhat confusing name. It accepts a list of usernames and of group names in standard smb.conf notation.
See also domain admin group, domain logons
Default: no domain guests
Example: domain guest group = nobody @guest
If set to true, the Samba server will serve Windows 95/98 Domain logons for the workgroup it is in. Samba 2.2 also has limited capability to act as a domain controller for Windows NT 4 Domains. For more details on setting up this feature see the file DOMAINS.txt in the Samba documentation directory docs/ shipped with the source code.
Default: domain logons = no
Tell nmbd(8) to enable WAN-wide browse list collation. Setting this option causes nmbd to claim a special domain specific NetBIOS name that identifies it as a domain master browser for its given workgroup. Local master browsers in the same workgroup on broadcast-isolated subnets will give this nmbd their local browse lists, and then ask smbd(8) for a complete copy of the browse list for the whole wide area network. Browser clients will then contact their local master browser, and will receive the domain-wide browse list, instead of just the list for their broadcast-isolated subnet.
Note that Windows NT Primary Domain Controllers expect to be able to claim this workgroup specific special NetBIOS name that identifies them as domain master browsers for that workgroup by default (i.e. there is no way to prevent a Windows NT PDC from attempting to do this). This means that if this parameter is set and nmbd claims the special name for a workgroup before a Windows NT PDC is able to do so then cross subnet browsing will behave strangely and may fail.
If domain logons = yes , then the default behavior is to enable the domain master parameter. If domain logons is not enabled (the default setting), then neither will domain master be enabled by default.
Default: domain master = auto
There are certain directories on some systems (e.g., the /proc tree under Linux) that are either not of interest to clients or are infinitely deep (recursive). This parameter allows you to specify a comma-delimited list of directories that the server should always show as empty.
Note that Samba can be very fussy about the exact format of the "dont descend" entries. For example you may need ./proc instead of just /proc. Experimentation is the best policy :-)
Default: none (i.e., all directories are OK to descend)
Example: dont descend = /proc,/dev
The default behavior in Samba is to provide UNIX-like behavor where only the owner of a file/directory is able to change the permissions on it. However, this behavior is often confusing to DOS/Windows users. Enabling this parameter allows a user who has write access to the file (by whatever means) to modify the permissions on it. Note that a user belonging to the group owning the file will not be allowed to change permissions if the group is only granted read access. Ownership of the file/directory is not changed, only the permissions are modified.
Default: dos filemode = no
Under the DOS and Windows FAT filesystem, the finest granularity on time resolution is two seconds. Setting this parameter for a share causes Samba to round the reported time down to the nearest two second boundary when a query call that requires one second resolution is made to smbd(8) .
This option is mainly used as a compatibility option for Visual C++ when used against Samba shares. If oplocks are enabled on a share, Visual C++ uses two different time reading calls to check if a file has changed since it was last read. One of these calls uses a one-second granularity, the other uses a two second granularity. As the two second call rounds any odd second down, then if the file has a timestamp of an odd number of seconds then the two timestamps will not match and Visual C++ will keep reporting the file has changed. Setting this option causes the two timestamps to match, and Visual C++ is happy.
Default: dos filetime resolution = no
Under DOS and Windows, if a user can write to a file they can change the timestamp on it. Under POSIX semantics, only the owner of the file or root may change the timestamp. By default, Samba runs with POSIX semantics and refuses to change the timestamp on a file if the user smbd is acting on behalf of is not the file owner. Setting this option to True allows DOS semantics and smbd will change the file timestamp as DOS requires.
Default: dos filetimes = no
This boolean controls whether encrypted passwords will be negotiated with the client. Note that Windows NT 4.0 SP3 and above and also Windows 98 will by default expect encrypted passwords unless a registry entry is changed. To use encrypted passwords in Samba see the file ENCRYPTION.txt in the Samba documentation directory docs/ shipped with the source code.
In order for encrypted passwords to work correctly smbd(8) must either have access to a local smbpasswd(5) file (see the smbpasswd(8) program for information on how to set up and maintain this file), or set the security = [server|domain] parameter which causes smbd to authenticate against another server.
Default: encrypt passwords = no
This option enables a couple of enhancements to cross-subnet browse propogation that have been added in Samba but which are not standard in Microsoft implementations. These enhancements are currently only available in the HEAD Samba CVS tree (not Samba 2.2.x).
The first enhancement to browse propogation consists of a regular wildcard query to a Samba WINS server for all Domain Master Browsers, followed by a browse synchronisation with each of the returned DMBs. The second enhancement consists of a regular randomised browse synchronisation with all currently known DMBs.
You may wish to disable this option if you have a problem with empty workgroups not disappearing from browse lists. Due to the restrictions of the browse protocols these enhancements can cause a empty workgroup to stay around forever which can be annoying.
In general you should leave this option enabled as it makes cross-subnet browse propogation much more reliable.
Default: enhanced browsing = yes
The concept of a "port" is fairly foreign to UNIX hosts. Under Windows NT/2000 print servers, a port is associated with a port monitor and generally takes the form of a local port (i.e. LPT1:, COM1:, FILE:) or a remote port (i.e. LPD Port Monitor, etc...). By default, Samba has only one port defined--"Samba Printer Port". Under Windows NT/2000, all printers must have a valid port name. If you wish to have a list of ports displayed (smbd does not use a port name for anything) other than the default "Samba Printer Port", you can define enumports command to point to a program which should generate a list of ports, one per line, to standard output. This listing will then be used in response to the level 1 and 2 EnumPorts() RPC.
Default: no enumports command
Example: enumports command = /usr/bin/listports
This is a synonym for preexec.
NTFS and Windows VFAT file systems keep a create time for all files and directories. This is not the same as the ctime - status change time - that Unix keeps, so Samba by default reports the earliest of the various times Unix does keep. Setting this parameter for a share causes Samba to always report midnight 1-1-1980 as the create time for directories.
This option is mainly used as a compatibility option for Visual C++ when used against Samba shares. Visual C++ generated makefiles have the object directory as a dependency for each object file, and a make rule to create the directory. Also, when NMAKE compares timestamps it uses the creation time when examining a directory. Thus the object directory will be created if it does not exist, but once it does exist it will always have an earlier timestamp than the object files it contains.
However, Unix time semantics mean that the create time reported by Samba will be updated whenever a file is created or or deleted in the directory. NMAKE finds all object files in the object directory. The timestamp of the last one built is then compared to the timestamp of the object dircetory. If the directory's timestamp if newer, then all object files will be rebuilt. Enabling this option ensures directories always predate their contents and an NMAKE build will proceed as expected.
Default: fake directory create times = no
Oplocks are the way that SMB clients get permission from a server to locally cache file operations. If a server grants an oplock (opportunistic lock) then the client is free to assume that it is the only one accessing the file and it will aggressively cache file data. With some oplock types the client may even cache file open/close operations. This can give enormous performance benefits.
When you set fake oplocks = yes, smbd(8) will always grant oplock requests no matter how many clients are using the file.
It is generally much better to use the real oplocks support rather than this parameter.
If you enable this option on all read-only shares or shares that you know will only be accessed from one client at a time such as physically read-only media like CDROMs, you will see a big performance improvement on many operations. If you enable this option on shares where multiple clients may be accessing the files read-write at the same time you can get data corruption. Use this option carefully!
Default: fake oplocks = no
This parameter allows the Samba administrator to stop smbd(8) from following symbolic links in a particular share. Setting this parameter to no prevents any file or directory that is a symbolic link from being followed (the user will get an error). This option is very useful to stop users from adding a symbolic link to /etc/passwd in their home directory for instance. However it will slow filename lookups down slightly.
This option is enabled (i.e. smbd will follow symbolic links) by default.
Default: follow symlinks = yes
This parameter specifies a set of UNIX mode bit permissions that will always be set on a file created by Samba. This is done by bitwise 'OR'ing these bits onto the mode bits of a file that is being created or having its permissions changed. The default for this parameter is (in octal) 000. The modes in this parameter are bitwise 'OR'ed onto the file mode after the mask set in the create mask parameter is applied.
Note that by default this parameter does not apply to permissions set by Windows NT/2000 ACL editors. If the administrator wishes to enforce this mask on access control lists also, they need to set the restrict acl with mask to true.
See also the parameter create mask for details on masking mode bits on files.
See also the inherit permissions parameter.
Default: force create mode = 000
Example: force create mode = 0755
would force all created files to have read and execute permissions set for 'group' and 'other' as well as the read/write/execute bits set for the 'user'.
This parameter specifies a set of UNIX mode bit permissions that will always be set on a directory created by Samba. This is done by bitwise 'OR'ing these bits onto the mode bits of a directory that is being created. The default for this parameter is (in octal) 0000 which will not add any extra permission bits to a created directory. This operation is done after the mode mask in the parameter directory mask is applied.
Note that by default this parameter does not apply to permissions set by Windows NT/2000 ACL editors. If the administrator wishes to enforce this mask on access control lists also, they need to set the restrict acl with mask to true.
See also the parameter directory mask for details on masking mode bits on created directories.
See also the inherit permissions parameter.
Default: force directory mode = 000
Example: force directory mode = 0755
would force all created directories to have read and execute permissions set for 'group' and 'other' as well as the read/write/execute bits set for the 'user'.
This parameter controls what UNIX permission bits can be modified when a Windows NT client is manipulating the UNIX permission on a directory using the native NT security dialog box.
This parameter is applied as a mask (OR'ed with) to the changed permission bits, thus forcing any bits in this mask that the user may have modified to be on. Essentially, one bits in this mask may be treated as a set of bits that, when modifying security on a directory, the user has always set to be 'on'.
If not set explicitly this parameter is 000, which allows a user to modify all the user/group/world permissions on a directory without restrictions.
Note that users who can access the Samba server through other means can easily bypass this restriction, so it is primarily useful for standalone "appliance" systems. Administrators of most normal systems will probably want to leave it set as 0000.
See also the directory security mask, security mask, force security mode parameters.
Default: force directory security mode = 0
Example: force directory security mode = 700
This specifies a UNIX group name that will be assigned as the default primary group for all users connecting to this service. This is useful for sharing files by ensuring that all access to files on service will use the named group for their permissions checking. Thus, by assigning permissions for this group to the files and directories within this service the Samba administrator can restrict or allow sharing of these files.
In Samba 2.0.5 and above this parameter has extended functionality in the following way. If the group name listed here has a '+' character prepended to it then the current user accessing the share only has the primary group default assigned to this group if they are already assigned as a member of that group. This allows an administrator to decide that only users who are already in a particular group will create files with group ownership set to that group. This gives a finer granularity of ownership assignment. For example, the setting force group = +sys means that only users who are already in group sys will have their default primary group assigned to sys when accessing this Samba share. All other users will retain their ordinary primary group.
If the force user parameter is also set the group specified in force group will override the primary group set in force user.
See also force user.
Default: no forced group
Example: force group = agroup
This parameter controls what UNIX permission bits can be modified when a Windows NT client is manipulating the UNIX permission on a file using the native NT security dialog box.
This parameter is applied as a mask (OR'ed with) to the changed permission bits, thus forcing any bits in this mask that the user may have modified to be on. Essentially, one bits in this mask may be treated as a set of bits that, when modifying security on a file, the user has always set to be 'on'.
If not set explicitly this parameter is set to 0, and allows a user to modify all the user/group/world permissions on a file, with no restrictions.
Note that users who can access the Samba server through other means can easily bypass this restriction, so it is primarily useful for standalone "appliance" systems. Administrators of most normal systems will probably want to leave this set to 0000.
See also the force directory security mode, directory security mask, security mask parameters.
Default: force security mode = 0
Example: force security mode = 700
This specifies a UNIX user name that will be assigned as the default user for all users connecting to this service. This is useful for sharing files. You should also use it carefully as using it incorrectly can cause security problems.
This user name only gets used once a connection is established. Thus clients still need to connect as a valid user and supply a valid password. Once connected, all file operations will be performed as the "forced user", no matter what username the client connected as. This can be very useful.
In Samba 2.0.5 and above this parameter also causes the primary group of the forced user to be used as the primary group for all file activity. Prior to 2.0.5 the primary group was left as the primary group of the connecting user (this was a bug).
See also force group
Default: no forced user
Example: force user = auser
This parameter allows the administrator to configure the string that specifies the type of filesystem a share is using that is reported by smbd(8) when a client queries the filesystem type for a share. The default type is NTFS for compatibility with Windows NT but this can be changed to other strings such as Samba or FAT if required.
Default: fstype = NTFS
Example: fstype = Samba
This is a tuning option. When this is enabled a caching algorithm will be used to reduce the time taken for getwd() calls. This can have a significant impact on performance, especially when the wide links parameter is set to False.
Default: getwd cache = yes
Synonym for force group.
This is a username which will be used for access to services which are specified as guest ok (see below). Whatever privileges this user has will be available to any client connecting to the guest service. Typically this user will exist in the password file, but will not have a valid login. The user account "ftp" is often a good choice for this parameter. If a username is specified in a given service, the specified username overrides this one.
One some systems the default guest account "nobody" may not be able to print. Use another account in this case. You should test this by trying to log in as your guest user (perhaps by using the su - command) and trying to print using the system print command such as lpr(1) or lp(1).
Default: specified at compile time, usually "nobody"
Example: guest account = ftp
If this parameter is yes for a service, then no password is required to connect to the service. Privileges will be those of the guest account.
See the section below on security for more information about this option.
Default: guest ok = no
If this parameter is yes for a service, then only guest connections to the service are permitted. This parameter will have no effect if guest ok is not set for the service.
See the section below on security for more information about this option.
Default: guest only = no
This is a boolean parameter that controls whether files starting with a dot appear as hidden files.
Default: hide dot files = yes
This is a list of files or directories that are not visible but are accessible. The DOS 'hidden' attribute is applied to any files or directories that match.
Each entry in the list must be separated by a '/', which allows spaces to be included in the entry. '*' and '?' can be used to specify multiple files or directories as in DOS wildcards.
Each entry must be a Unix path, not a DOS path and must not include the Unix directory separator '/'.
Note that the case sensitivity option is applicable in hiding files.
Setting this parameter will affect the performance of Samba, as it will be forced to check all files and directories for a match as they are scanned.
See also hide dot files, veto files and case sensitive.
Default: no file are hidden
Example: hide files = /.*/DesktopFolderDB/TrashFor%m/resource.frk/
The above example is based on files that the Macintosh SMB client (DAVE) available from Thursby creates for internal use, and also still hides all files beginning with a dot.
This parameter toggles the hiding of local UNIX users (root, wheel, floppy, etc) from remote clients.
Default: hide local users = no
Ifnis homedir is True, and smbd(8) is also acting as a Win95/98 logon server then this parameter specifies the NIS (or YP) map from which the server for the user's home directory should be extracted. At present, only the Sun auto.home map format is understood. The form of the map is:
username server:/some/file/system
and the program will extract the servername from before the first ':'. There should probably be a better parsing system that copes with different map formats and also Amd (another automounter) maps.
NOTE :A working NIS client is required on the system for this option to work.
See also nis homedir , domain logons .
Default: homedir map = <empty string>
Example: homedir map = amd.homedir
This boolean parameter is only available if Samba has been configured and compiled with the --with-msdfs option. If set to yes, Samba will act as a Dfs server, and allow Dfs-aware clients to browse Dfs trees hosted on the server.</
