Yes, if you are not using EAP. Since you are - you can't rewrite usernames. Have users use ntdomain style usernames: domain\username. You can autheticate those from a database containing only username as user name (enable ntdomain and nt domain hack). Ivan Kalik Kalik Informatika ISP - List info/subscribe/unsubscribe?
