- The idmap_script plugin is a substitute for the idmap_tdb2
- backend used by winbindd for storing SID/uid/gid mapping tables
- in clustered environments with Samba and CTDB. It is a read only
- backend that uses a script to perform mapping.
+ The idmap_script plugin provides a means for winbindd to obtain
+ id mappings from an external program.

<para>
- It was developed out of the idmap_tdb2 back end and does not store
- SID/uid/gid mappings in a TDB, since the winbind_cache tdb will
- store the mappings once they are provided.
+ This is a read-only backend.

+ <para>
+ The functionality of this module was originally provided by the
+ idmap:script option of the idmap_tdb2 backend and extracted into
+ the idmap_script module. In contrast to the original idmap_tdb2
+ implementation, the idmap_script module does not store the obtained
+ mappings in a TDB database. Caching is done in Samba's general
+ idmap cache.
