198 * This next constant specifies the version number of the PASSDB interface
199 * this SAMBA will load. Increment this if *ANY* changes are made to the interface.
200 * Changed interface to fix int -> size_t problems. JRA.
201 * There's no point in allocating arrays in
202 * samr_lookup_rids twice. It was done in the srv_samr_nt.c code as well as in
203 * the pdb module. Remove the latter, this might happen more often. VL.
204 * changed to version 14 to move lookup_rids and lookup_names to return
205 * enum lsa_SidType rather than uint32.
206 * Changed to 16 for access to the trusted domain passwords (obnox).
207 * Changed to 17, the sampwent interface is gone.
