       idmap_tdb - Samba's idmap_tdb Backend for Winbind


       The idmap_tdb plugin is the default backend used by winbindd for storing SID/uid/gid
       mapping tables.

       In contrast to read only backends like idmap_rid, it is an allocating backend: This means
       that it needs to allocate new user and group IDs in order to create new mappings.


       range = low - high
           Defines the available matching uid and gid range for which the backend is


       This example shows how tdb is used as the default idmap backend. This configured range is
       used for uid and gid allocation.

                # "backend = tdb" is redundant here since it is the default
                idmap config * : backend = tdb
                idmap config * : range = 1000000-2000000


       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.
