</refnamediv>
<refsynopsisdiv>
<title>DESCRIPTION</title>
<para>The idmap_ad plugin provides a way for Winbind to read
id mappings from an AD server that uses RFC2307/SFU schema
extensions. This module implements only the "idmap"
API, and is READONLY. Mappings must be provided in advance
by the administrator by adding the posixAccount/posixGroup
classes and relative attribute/value pairs to the user and
group objects in the AD.</para>
</refsynopsisdiv>

<title>IDMAP OPTIONS</title>
<variablelist>
<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 acts as a filter.
If specified any UID or GID stored in AD that fall outside the
range is ignored and the corresponding map is discarded.
It is intended as a way to avoid accidental UID/GID overlaps
between local and remotely defined IDs.
</para></listitem>
</varlistentry>
<varlistentry>
<term>schema_mode = <rfc2307 | sfu ></term>
<listitem><para>
Defines the schema that idmap_ad should use when querying
Active Directory regarding user and group information.
This can be either the RFC2307 schema support included
in Windows 2003 R2 or the Service for Unix (SFU) schema.

<title>EXAMPLES</title>
<para>
The following example shows how to retrieve idmappings from our principal and
trusted AD domains. If trusted domains are present id conflicts must be
resolved beforehand, there is no
guarantee on the order conflicting mappings would be resolved at this point.
This example also shows how to leave a small non conflicting range for local
id allocation that may be used in internal backends like BUILTIN.

<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.
