As Donald points out, NetBIOS domains are allowed more characters than the code currently allows. Change the test to one that checks for disallowed characters instead. Also, I can't find anything that says that '@' is not allowed in a username. Might as well allow that too. Worst case, the server will reject the username. Reported-by: Donald R.
