NAME
       idmap_ad - Samba's idmap_ad Backend for Winbind

DESCRIPTION
       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.

IDMAP OPTIONS
       range = low - high
           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.

       schema_mode = <rfc2307 | sfu >
           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.

EXAMPLES
       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.

                [global]
                idmap backend = tdb
                idmap uid = 1000000-1999999
                idmap gid = 1000000-1999999

                idmap config CORP : backend  = ad
                idmap config CORP : range = 1000-999999
