Merge from 3.0:

source/libsmb/ntlmssp.c:
Picked up by the build farm - despite all my efforts, security=server was
broken by my NTLM2 commit.  This should correctly cause the NTLM2 case
not to be negotiated when 'security=server' is in effect.

testsuide/build_farm/runlist:
Without 'non unix accounts' we can't test security=domain on the build farm.

source/rpc_server/srv_samr_nt.c:
Match Win2k and return 'invalid parameter' for creating of a new account with
account flags of 0.
