	file for the Samba suite. <tt class="filename">smb.conf</tt> contains  
	runtime configuration information for the Samba programs. The <tt class="filename">smb.conf</tt> file 
	is designed to be configured and  administered by the <a href="swat.8.html"><span class="citerefentry"><span class="refentrytitle">swat</span>(8)</span></a> program. The complete
	description of the file format and possible parameters held within
	are here for reference purposes.</p></div><div class="refsect1" lang="en"><a name="FILEFORMATSECT"></a><h2>FILE FORMAT</h2><p>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</p><p><i class="replaceable"><tt>name</tt></i> = <i class="replaceable"><tt>value
	</tt></i></p><p>The file is line-based - that is, each newline-terminated 
	line represents either a comment, a section name or a parameter.</p><p>Section and parameter names are not case sensitive.</p><p>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.</p><p>Any line beginning with a semicolon (';') or a hash ('#') 
	character is ignored, as are lines containing only whitespace.</p><p>Any line ending in a '\' is continued
	on the next line in the customary UNIX fashion.</p><p>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.</p></div><div class="refsect1" lang="en"><h2>SECTION DESCRIPTIONS</h2><p>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.</p><p>There are three special sections, [global],
	[homes] and [printers], which are
	described under <span class="emphasis"><em>special sections</em></span>. The
	following notes apply to ordinary section descriptions.</p><p>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.</p><p>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).</p><p>Sections may be designated <span class="emphasis"><em>guest</em></span> services,
	in which case no password is required to access them. A specified 
	UNIX <span class="emphasis"><em>guest account</em></span> is used to define access
	privileges in this case.</p><p>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.</p><p>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.</p><p>The following sample section defines a file space share. 
	The user has write access to the path <tt class="filename">/home/bar</tt>. 
	The share is accessed via the share name "foo":</p><pre class="screen">
<tt class="computeroutput">
[foo]
	path = /home/bar
	read only = no
</tt>
</pre><p>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 <span class="emphasis"><em>guest ok</em></span> parameter means 
	access will be permitted as the default guest user (specified 
	elsewhere):</p><pre class="screen">
<tt class="computeroutput">
[aprinter]
	path = /usr/spool/public
	read only = yes
	printable = yes
	guest ok = yes
</tt>
</pre></div><div class="refsect1" lang="en"><h2>SPECIAL SECTIONS</h2><div class="refsect2" lang="en"><h3>The [global] section</h3><p>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.</p></div><div class="refsect2" lang="en"><a name="HOMESECT"></a><h3>The [homes] section</h3><p>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.</p><p>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.</p><p>Some modifications are then made to the newly 
		created share:</p><div class="itemizedlist"><ul type="disc"><li><p>The share name is changed from homes to 
		the located username.</p></li><li><p>If no path was given, the path is set to
		the user's home directory.</p></li></ul></div><p>If you decide to use a <span class="emphasis"><em>path =</em></span> line 
		in your [homes] section then you may find it useful 
		to use the %S macro. For example :</p><p><b class="userinput"><tt>path = /data/pchome/%S</tt></b></p><p>would be useful if you have different home directories 
		for your PCs than for UNIX access.</p><p>This is a fast and simple way to give a large number 
		of clients access to their home directories with a minimum 
		of fuss.</p><p>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.</p><p>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:</p><pre class="screen">
<tt class="computeroutput">
[homes]
	read only = no
</tt>
</pre><p>An important point is that if guest access is specified 
		in the [homes] section, all home directories will be 
		visible to all clients <span class="emphasis"><em>without a password</em></span>. 
		In the very unlikely event that this is actually desirable, it 
		would be wise to also specify <span class="emphasis"><em>read only
		access</em></span>.</p><p>Note that the <span class="emphasis"><em>browseable</em></span> 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 <span class="emphasis"><em>browseable = no</em></span> in
		the [homes] section will hide the [homes] share but make
		any auto home directories visible.</p></div><div class="refsect2" lang="en"><a name="PRINTERSSECT"></a><h3>The [printers] section</h3><p>This section works like [homes], 
		but for printers.</p><p>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.</p><p>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.</p><p>A few modifications are then made to the newly created 
		share:</p><div class="itemizedlist"><ul type="disc"><li><p>The share name is set to the located printer 
		name</p></li><li><p>If no printer name was given, the printer name 
		is set to the located printer name</p></li><li><p>If the share does not permit guest access and 
		no username was given, the username is set to the located 
		printer name.</p></li></ul></div><p>Note that the [printers] service MUST be 
		printable - if you specify otherwise, the server will refuse 
		to load the configuration file.</p><p>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:</p><pre class="screen"><tt class="computeroutput">
[printers]
	path = /usr/spool/public
	guest ok = yes
	printable = yes 
</tt></pre><p>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:</p><pre class="screen">
<tt class="computeroutput">
alias|alias|alias|alias...    
</tt>
</pre><p>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.</p><p>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 ('|').</p><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p>On SYSV systems which use lpstat to determine what 
		printers are defined on the system you may be able to use

		for more details.</p></div></div></div><div class="refsect1" lang="en"><h2>PARAMETERS</h2><p>parameters define the specific attributes of sections.</p><p>Some parameters are specific to the [global] section
	(e.g., <span class="emphasis"><em>security</em></span>).  Some parameters are usable 
	in all sections (e.g., <span class="emphasis"><em>create mode</em></span>). 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 <span class="emphasis"><em>G</em></span> 
	in parentheses indicates that a parameter is specific to the
	[global] section. The letter <span class="emphasis"><em>S</em></span>
	indicates that a parameter can be specified in a service specific
	section. Note that all <span class="emphasis"><em>S</em></span> parameters can also be specified in 
	the [global] section - in which case they will define
	the default behavior for all services.</p><p>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.</p></div><div class="refsect1" lang="en"><h2>VARIABLE SUBSTITUTIONS</h2><p>Many of the strings that are settable in the config file

	/tmp/john" if the user connected with the username john.</p><p>These substitutions are mostly noted in the descriptions below, 
	but there are some general substitutions which apply whenever they 
	might be relevant. These are:</p><div class="variablelist"><dl><dt><span class="term">%U</span></dt><dd><p>session user name (the user name that the client

    When smbd is serving Printer Drivers to Windows NT/2k/XP clients, each printer on the Samba
    server has a Device Mode which defines things such as paper size and
    orientation and duplex settings.  The device mode can only correctly be
    generated by the printer driver itself (which can only be executed on a
    Win32 platform).  Because smbd is unable to execute the driver code
    to generate the device mode, the default behavior is to set this field
    to NULL.
    </p><p>Most problems with serving printer drivers to Windows NT/2k/XP clients
    can be traced to a problem with the generated device mode.  Certain drivers
    will do things such as crashing the client's Explorer.exe with a NULL devmode.
    However, other printer drivers can cause the client's spooler service
    (spoolsv.exe) to die if the devmode was not created by the driver itself
    (i.e. smbd generates a default devmode).
    </p><p>This parameter should be used with care and tested with the printer
    driver in question.  It is better to leave the device mode to NULL
    and let the Windows client set the correct values.  Because drivers do not
    do this all the time, setting <b class="command">default devmode = yes</b>
    will instruct smbd to generate a default one.

    in that domain, and will use cryptographically authenticated RPC calls

    and then contacting each server returned in the list of IP 
    addresses from the name resolution source. </p><p>If the list of servers contains both names/IP's and the '*'
    character, the list is treated as a list of preferred

	This boolean parameter was added to fix the problems that people have been
	having with storing user profiles on Samba shares from Windows 2000 or
	Windows XP clients. New versions of Windows 2000 or Windows XP service
	packs do security ACL checking on the owner and ability to write of the
	profile directory stored on a local workstation when copied from a Samba
	share.
</p><p>When not in domain mode with winbindd then the security info copied
	onto the local workstation has no meaning to the logged in user (SID) on
	that workstation so the profile storing fails. Adding this parameter
	onto a share used for profile storage changes two things about the
	returned Windows ACL. Firstly it changes the owner and group owner
	of all reported files and directories to be BUILTIN\\Administrators,
	BUILTIN\\Users respectively (SIDs S-1-5-32-544, S-1-5-32-545). Secondly
	it adds an ACE entry of "Full Control" to the SID BUILTIN\\Users to
	every returned ACL. This will allow any Windows 2000 or XP workstation
	user to access the profile.</p><p>Note that if you have multiple users logging
	on to a workstation then in order to prevent them from being able to access
	each others profiles you must remove the "Bypass traverse checking" advanced
	user right. This will prevent access to other users profile directories as
	the top level profile directory (named after the user) is created by the
	workstation profile code and has an ACL restricting entry to the directory
	tree to the owning user.

    a mapping of usernames from the clients to the server. This can be 
    used for several purposes. The most common is to map usernames 
    that users use on DOS or Windows machines to those that the UNIX 
    box uses. The other is to map multiple users to a single username 
    so that they can more easily share files.</p><p>The map file is parsed line by line. Each line should 
    contain a single UNIX username on the left then a '=' followed 
    by a list of usernames on the right. The list of usernames on the 
    right may contain names of the form @group in which case they 
    will match any UNIX username in that group. The special client 
    name '*' is a wildcard and matches any name. Each line of the 
    map file may be up to 1023 characters long.</p><p>The file is processed on each line by taking the 
    supplied username and comparing it with each username on the right 
    hand side of the '=' signs. If the supplied name matches any of 
    the names on the right hand side then it is replaced with the name 
    on the left. Processing then continues with the next line.</p><p>If any line begins with a '#' or a ';' then it is ignored</p><p>If any line begins with an '!' then the processing
    will stop after that line if a mapping was done by the line.
    Otherwise mapping continues with every line being processed.
    Using '!' is most useful when you have a wildcard mapping line
    later in the file.</p><p>For example to map from the name <tt class="constant">admin</tt>
    or <tt class="constant">administrator</tt> to the UNIX name <tt class="constant">
    root</tt> you would use:</p><p><b class="command">root = admin administrator</b></p><p>Or to map anyone in the UNIX group <tt class="constant">system</tt>
    to the UNIX name <tt class="constant">sys</tt> you would use:</p><p><b class="command">sys = @system</b></p><p>You can have as many mappings as you like in a username map file.</p><p>If your system supports the NIS NETGROUP option then
    the netgroup database is checked before the <tt class="filename">/etc/group
    </tt> database for matching groups.</p><p>You can map Windows usernames that have spaces in them
     by using double quotes around the name. For example:</p><p><b class="command">tridge = "Andrew Tridgell"</b></p><p>would map the windows username "Andrew Tridgell" to the
    unix username "tridge".</p><p>The following example would map mary and fred to the
    unix user sys, and map the rest to guest. Note the use of the
    '!' to tell Samba to stop processing if it gets a match on
    that line.</p><pre class="programlisting">
!sys = mary fred
guest = *
</pre><p>Note that the remapping is applied to all occurrences
    of usernames. Thus if you connect to \\server\fred and <tt class="constant">
    fred</tt> is remapped to <tt class="constant">mary</tt> then you
    will actually be connecting to \\server\mary and will need to
    supply a password suitable for <tt class="constant">mary</tt> not
    <tt class="constant">fred</tt>. The only exception to this is the
    username passed to the <a href="#PASSWORDSERVER"><i class="parameter"><tt>
    password server</tt></i></a> (if you have one). The password
    server will receive whatever username the client supplies without
    modification.</p><p>Also note that no reverse mapping is done. The main effect
    this has is with printing. Users who have been mapped may have
    trouble deleting print jobs as PrintManager under WfWg will think
    they don't own the print job.</p><p>Default: <span class="emphasis"><em>no username map</em></span></p><p>Example: <b class="command">username map = /usr/local/samba/lib/users.map</b></p></dd><dt><span class="term"><a name="USERS"></a>users (S)<a class="indexterm" name="id2897868"></a></span></dt><dd><p>Synonym for <a href="#USERNAME"><i class="parameter"><tt>
