278 * This next constant specifies the version number of the PASSDB interface

284 * changed to version 14 to move lookup_rids and lookup_names to return
285 * enum lsa_SidType rather than uint32_t.
286 * Changed to 16 for access to the trusted domain passwords (obnox).
287 * Changed to 17, the sampwent interface is gone.
288 * Changed to 18, pdb_rid_algorithm -> pdb_capabilities
289 * Changed to 19, removed uid_to_rid
