idmap_tdb - Samba's idmap_tdb Backend for Winbind

       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.

Samba 4.22.3-Ubuntu-4.22.3+dfs                     07/21/2025                                       IDMAP_TDB(8)

       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.

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

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

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