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

       Source project similar to the way the Linux kernel is developed.
