313 * samr_lookup_rids twice. It was done in the srv_samr_nt.c code as well as in
314 * the pdb module. Remove the latter, this might happen more often. VL.
315 * changed to version 14 to move lookup_rids and lookup_names to return
316 * enum lsa_SidType rather than uint32_t.
317 * Changed to 16 for access to the trusted domain passwords (obnox).
318 * Changed to 17, the sampwent interface is gone.
319 * Changed to 18, pdb_rid_algorithm -> pdb_capabilities
320 * Changed to 19, removed uid_to_rid
321 * Changed to 20, pdb_secret calls
