<refpurpose>Samba's idmap_ldap Backend for Winbind</refpurpose>
</refnamediv>
<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 "idmap" and
"idmap alloc" APIs.

<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 "ldap idmap suffix" option from smb.conf.
</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>
<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 "idmap uid" and
"idmap gid" options from smb.conf.

<listitem><para>

should be used.

<listitem><para>

<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.
