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
