New Revision: 11370
WebSVN: http://websvn.samba.org/cgi-bin/viewcvs.cgi?view=rev&root=samba&rev=11370
Log:
Samba4 now passes it's own RPC-SAMLOGON test again.
This avoids the nasty user at DOMAIN test for now, as it has very odd
semantics with NTLMv2.
Allow only user accounts to do an interactive login.
