|
|---|
| 21 | <para>The idmap_rid backend provides a way to use an algorithmic
|
|---|
| 22 | mapping scheme to map UIDs/GIDs and SIDs. No database is required
|
|---|
| 23 | in this case as the mapping is deterministic.</para>

|
|---|
| 33 | Defines the available matching uid and gid range for which the
|
|---|
| 34 | backend is authoritative. Note that the range acts as a filter.
|
|---|
| 35 | If algorithmically determined UID or GID fall outside the
|
|---|
| 36 | range, they are ignored and the corresponding map is discarded.
|
|---|
| 37 | It is intended as a way to avoid accidental UID/GID overlaps
|
|---|
| 38 | between local and remotely defined IDs.

|
|---|
| 45 | Defines the base integer used to build SIDs out of an UID or a GID,
|
|---|
| 46 | and to rebase the UID or GID to be obtained from a SID. User RIDs
|
|---|
| 47 | by default start at 1000 (512 hexadecimal), this means a good value
|
|---|
| 48 | for base_rid can be 1000 as the resulting ID is calculated this way:
|
|---|
| 49 | ID = RID - BASE_RID + LOW RANGE ID.
