NAME

6       idmap_rid - Samba's idmap_rid Backend for Winbind
7

DESCRIPTION

9       The  idmap_rid  backend  provides  a  way to use an algorithmic mapping
10       scheme to map UIDs/GIDs and SIDs. No database is required in this  case
11       as the mapping is deterministic.
12

IDMAP OPTIONS

14       range = low - high
15          Defines the available matching uid and gid range for which the back‐
16          end is authoritative. Note that the range acts as a filter. If algo‐
17          rithmically  determined  UID or GID fall outside the range, they are
18          ignored and the corresponding map is discarded. It is intended as  a
19          way  to avoid accidental UID/GID overlaps between local and remotely
20          defined IDs.
21
22       base_rid = INTEGER
23          Defines the base integer used to build SIDs out of an UID or a  GID,
24          and to rebase the UID or GID to be obtained from a SID. User RIDs by
25          default start at 1000 (512 hexadecimal), this means a good value for
26          base_rid  can be 1000 as the resulting ID is calculated this way: ID
27          = RID - BASE_RID + LOW RANGE ID.

EXAMPLES

30       This example shows how to configure 2 domains with idmap_rid
31
32
33            [global]
34                idmap domains = MAIN TRUSTED1
35
36                idmap config MAIN:backend      = rid
37                idmap config MAIN:base_rid     = 1000
38                idmap config MAIN:range        = 10000 - 49999
39
40                idmap config TRUSTED1:backend  = rid
41                idmap config TRUSTED1:base_rid = 1000
42                idmap config TRUSTED1:range    = 50000 - 99999

AUTHOR

46       The original Samba software  and  related  utilities  were  created  by
47       Andrew  Tridgell.  Samba  is now developed by the Samba Team as an Open
48       Source project similar to the way the Linux kernel is developed.
