	authenticated session down into LDB. This associates a session info structure with the open LDB, allowing a future ldb_ntacl module to allow/deny operations on that basis. Along the way, I cleaned up a few things, and added new helper functions to assist. In particular the LSA pipe uses simpler queries for some of the setup. In ldap_server, I have removed the 'ldasrv:hacked' module, which hasn't been worked on (other than making it continue to compile) since January, and I think the features of this module are being put into ldb anyway. I have also changed the partitions in ldap_server to be initialised after the connection, with the private pointer used to associate the ldb with the incoming session.
