207 * This next constant specifies the version number of the PASSDB interface
208 * this SAMBA will load. Increment this if *ANY* changes are made to the interface.
209 * Changed interface to fix int -> size_t problems. JRA.
210 * There's no point in allocating arrays in
211 * samr_lookup_rids twice. It was done in the srv_samr_nt.c code as well as in
212 * the pdb module. Remove the latter, this might happen more often. VL.
213 * changed to version 14 to move lookup_rids and lookup_names to return
214 * enum lsa_SidType rather than uint32.
215 * Changed to 16 for access to the trusted domain passwords (obnox).
216 * Changed to 17, the sampwent interface is gone.
217 * Changed to 18, pdb_rid_algorithm -> pdb_capabilities
