Hi Henrik and Chris Thanks for your reply. In my system we have automatic authenticate on my proxy. For example, client logon to domain she can use proxy automatically. But for other clients who don't login to my domain they must login with old NT format i.e. "MYDOMAIN\username". How every I found that windows 2003 have new style of login name i.e. "username@MYDOMAIN". For information of Kinkie advice me to code auth helper. Any way to solve this ? I'm not sure that current samba helper is support new style of login name.
