This is a first working version of net rpc vampire. First do a net rpc
getsid, then join as a BDC, and then watch net rpc vampire suck out the good stuff out of a PDC :-). It's not perfect, but it does quite a bit for me. Watch out for more. Volker (This used to be commit f0d7ac9feb5844c93789344285b1d66f480209ba)
