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. The allocator can be provided by the idmap_tdb backend itself or by any other allocating backend like
       idmap_ldap or idmap_tdb2. This is configured with the parameter idmap alloc backend.

       Note that in order for this (or any other allocating) backend to function at all, the default backend needs to be writeable. The ranges
       used for uid and gid allocation are the default ranges configured by "idmap uid" and "idmap gid".

       Furthermore, since there is only one global allocating backend responsible for all domains using writeable idmap backends, any explicitly
       configured domain with idmap backend tdb should have the same range as the default range, since it needs to use the global uid / gid
       allocator. See the example below.

IDMAP OPTIONS

       range = low - high
	   Defines the available matching uid and gid range for which the backend is authoritative. If the parameter is absent, Winbind fails over
	   to use the "idmap uid" and "idmap gid" options from smb.conf.

EXAMPLES

       This example shows how tdb is used as a the default idmap backend. It configures the idmap range through the global options for all domains
       encountered. This same range is used for uid/gid allocation.

		[global]
		# "idmap backend = tdb" is redundant here since it is the default
		idmap backend = tdb
		idmap uid = 1000000-2000000
		idmap gid = 1000000-2000000

       This (rather theoretical) example shows how tdb can be used as the allocating backend while ldap is the default backend used to store the
       mappings. It adds an explicit configuration for some domain DOM1, that uses the tdb idmap backend. Note that the same range as the default
       uid/gid range is used, since the allocator has to serve both the default backend and the explicitly configured domain DOM1.

		[global]
		idmap backend = ldap
		idmap uid = 1000000-2000000
		idmap gid = 1000000-2000000
		# use a different uid/gid allocator:
		idmap alloc backend = tdb

		idmap config DOM1 : backend = tdb
		idmap config DOM1 : range = 1000000-2000000
