Try to gain a bit more consistancy in the output of usernames from ntlm_auth:

Instead of returning a name in DOMAIN\user format, we now return it in the
same way that nsswtich does - following the rules of 'winbind use default
domain', in the correct case and with the correct seperator.

This should help sites who are using Squid or the new SASL code I'm working
on, to match back to their unix usernames.

--

Get the DOMAIN\username around the right way (I had username\domain...)

Push the unix username into utf8 for it's trip across the socket.
