libsmb/smbdes.c: #ifdef'ed out code prior to removal.
rpc_client/cli_pipe.c: Inlined code removed from smbdes.c rpc_server/srv_samr.c: Fixed unused variable warning. rpc_server/srv_util.c: Inlined code removed from smbdes.c Luke - the above changes are the first part of the changes you and I discussed as being neccessary at the CIFS conference. *PLEASE REVIEW THESE CHANGES* - make sure I haven't broken any of the authenticated DCE/RPC code. smbd/nttrans.c: Fixed to allow NT5.0beta2 to use Samba shares with NT SMB support. smbd/open.c: Fixed mkdir when called from nttrans calls. smbd/server.c: Set correct size for strcpy of global_myworkgroup. Jeremy.
