Attached is my proposed set of changes. They pass 'make test' in Samba3
and resolve the delay in Samba4's 'make test' around the schannel tests.
(I'm chasing down some apparently unrelated issues there, but I'll
ensure it passes 'make test' there too).
I think I've followed the pattern given above correctly. If someone
could please push/review/comment I would appreciate it.
