<title>DESCRIPTION</title>
|
|
<para>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.</para>

<listitem><para>
|
|
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.

<term>base_rid = INTEGER</term>
|
|
<listitem><para>
|
|
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.

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