Sommaire

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.
Use of this parameter is deprecated.

EXAMPLES

This example shows how to configure a domain with idmap_rid

 
 
         [global]
         idmap backend = tdb
         idmap uid = 1000000-1999999
         idmap gid = 1000000-1999999
 
         idmap config TRUSTED : backend  = rid
         idmap config TRUSTED : range    = 50000 - 99999
