NAME

idmap_tdb - Samba's idmap_tdb Backend for Winbind

DESCRIPTION

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.

IDMAP OPTIONS

range = low - high

: Defines the available matching uid and gid range for which the backend is authoritative.

EXAMPLES

This example shows how tdb is used as a 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
