<refsynopsisdiv>
	<title>DESCRIPTION</title>

	<para>The idmap_ldap plugin provides a means for Winbind to
	store and retrieve SID/uid/gid mapping tables in an LDAP directory
	service.  The module implements both the &quot;idmap&quot; and
	&quot;idmap alloc&quot; APIs.

	<title>IDMAP OPTIONS</title>

	<variablelist>
		<varlistentry>
		<term>ldap_base_dn = DN</term>
		<listitem><para>
			Defines the directory base suffix to use when searching for
			SID/uid/gid mapping entries.  If not defined, idmap_ldap will default
			to using the &quot;ldap idmap suffix&quot; option from smb.conf.
		</para></listitem>
		</varlistentry>

		<varlistentry>
		<term>ldap_user_dn = DN</term>
		<listitem><para>
			Defines the user DN to be used for authentication. If absent an
			anonymous bind will be performed.
		</para></listitem>
		</varlistentry>

		<varlistentry>
		<term>ldap_url = ldap://server/</term>
		<listitem><para>
			Specifies the LDAP server to use when searching for existing
			SID/uid/gid map entries. If not defined, idmap_ldap will
			assume that ldap://localhost/ should be used.
		</para></listitem>

                <varlistentry>
		<term>range = low - high</term>
                <listitem><para>
			Defines the available matching uid and gid range for which the
			backend is authoritative.  Note that the range commonly matches
			the allocation range due to the fact that the same backend will
			store and retrieve SID/uid/gid mapping entries.  If the parameter
			is absent, Winbind fail over to use the &quot;idmap uid&quot; and
			&quot;idmap gid&quot; options from smb.conf.

	<title>EXAMPLES</title>

	<para>
	The follow sets of a LDAP configuration which uses a slave server
	running on localhost for fast fetching SID/gid/uid mappings, it
	implies correct configuration of referrals.
	The idmap alloc backend is pointed directly to the master to skip
	the referral (and consequent reconnection to the master) that the
	slave would return as allocation requires writing on the master.
	</para>

	<programlisting>
	[global]
	    idmap domains = ALLDOMAINS
	    idmap config ALLDOMAINS:default      = yes
	    idmap config ALLDOMAINS:backend      = ldap

	<title>NOTE</title>

	<para>In order to use authentication against ldap servers you may
	need to provide a DN and a password. To avoid exposing the password
	in plain text in the configuration file we store it into a security
	store. The &quot;net idmap &quot; command is used to store a secret
	for the DN specified in a specific idmap domain.

	<title>AUTHOR</title>

	<para>
	The original Samba software and related utilities
	were created by Andrew Tridgell. Samba is now developed
	by the Samba Team as an Open Source project similar
	to the way the Linux kernel is developed.
