NAME
       idmaprid - Samba's idmaprid Backend for Winbind

DESCRIPTION
       The  idmaprid  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.

       range = low - high
          Defines the available matching uid and gid range for which the back-
          end is authoritative. Note that the range acts as a filter. If algo-
          rithmically  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.

       baserid = 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
          baserid  can be 1000 as the resulting ID is calculated this way: ID
          = RID - BASERID + LOW RANGE ID.

EEXXAAMMPPLLEESS
       This example shows how to configure 2 domains with idmaprid


            [global]
                idmap domains = MAIN TRUSTED1

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

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


AUTHOR       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.
