<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>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>
	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.
