        <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 &quot;idmap&quot;
        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>

                        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.

                        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
        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.

        <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.
