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. Andrew Bartlett (This used to be commit 7a3a5a63612b2698a39f784859496c395505a79b)
