idmap_rid

IDMAP_RID(8)						    System Administration tools 					      IDMAP_RID(8)

NAME

       idmap_rid - Samba's idmap_rid Backend for Winbind

DESCRIPTION

       The idmap_rid backend provides a way to use an algorithmic mapping scheme to map UIDs/GIDs and SIDs. No database is required in this case
       as the mapping is deterministic.

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
	   algorithmically determined UID or GID fall outside the range, they are 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.

       base_rid = INTEGER
	   Defines the base integer used to build SIDs out of a UID or a GID, and to rebase the UID or GID to be obtained from a SID. This means
	   SIDs with a RID less than the base rid are filtered. The default is not to restrict the allowed rids at all, i.e. a base_rid value of
	   0. A good value for the base_rid can be 1000, since user RIDs by default start at 1000 (512 hexadecimal).

	   Use of this parameter is deprecated.

THE MAPPING FORMULAS

       The Unix ID for a RID is calculated this way:

			  ID = RID - BASE_RID + LOW_RANGE_ID.

       Correspondingly, the formula for calculating the RID for a given Unix ID is this:

			  RID = ID + BASE_RID - LOW_RANGE_ID.

EXAMPLES

       This example shows how to configure two domains with idmap_rid, the principal domain and a trusted domain, leaving the default id mapping
       scheme at tdb. The example also demonstrates the use of the base_rid parameter for the trusted domain.

		[global]
		security = domain
		workgroup = MAIN

		idmap backend = tdb
		idmap uid = 1000000-1999999
		idmap gid = 1000000-1999999

		idmap config MAIN : backend	= rid
		idmap config MAIN : range	= 10000 - 49999

		idmap config TRUSTED : backend	= rid
		idmap config TRUSTED : range	= 50000 - 99999
		idmap config TRUSTED : base_rid = 1000
