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
