| 22 | idmap_rid \- Samba\'s idmap_rid Backend for Winbind
|

| 23 | .SH "DESCRIPTION"
|
|---|
| 24 | .PP
|
|---|
| 25 | 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\&.

|

| 29 | .RS 4
|
|---|
| 30 | 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\&.

| 33 | base_rid = INTEGER
|
|---|
| 34 | .RS 4
|
|---|
| 35 | 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\&.
