IDMAP_RID(8)                                                                                    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 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
