Not at all.
It calls an external local program ("script") to retrieve the mapping
instead of incrementing a counter in a database (idmap.ldb, and
winbindd idmap backends tdb, tdb2, ldap) or calculating
the mappings with an algorithm (rid and autorid backends)

Just read the "IDMAP SCRIPT" section in the idmap_tdb2 manpage
for the details on what Richard extracted from the tdb2 backend.
