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 an UID or a GID,
	  and  to  rebase the UID or GID to be obtained from a SID. User RIDs
	  by default start at 1000 (512 hexadecimal), this means a good value
	  for  base_rid	 can  be  1000 as the resulting ID is calculated this
	  way: ID = RID - BASE_RID + LOW RANGE ID.

EXAMPLES
       This example shows how to configure 2 domains with idmap_rid


	    [global]
		idmap domains = MAIN TRUSTED1

		idmap config MAIN:backend      = rid
		idmap config MAIN:base_rid     = 1000
		idmap config MAIN:range	       = 10000 - 49999

		idmap config TRUSTED1:backend  = rid
		idmap config TRUSTED1:base_rid = 1000
		idmap config TRUSTED1:range    = 50000 - 99999

       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.
