It really isn't bizzare, because that is how it is designed to work. It uses the credentials you provide to authenticate the user, and logs it that way. --------------------------------------------- Chad E. Naugle Tech Support II, x. 7981 Travel Impressions, Ltd. >>> "Riccardo Castellani" <ric.castellani@xxxxxxxx> 11/17/2010 2:24 PM >>> I tested Squid authentication by ActiveDirectory LDAP. I tried to navigate in these 2 cases: A) from clients which are in workgroup: if I type credentials of a domain user, surfing works fine. B) from clients which are into domain: if I type credentials of my domain user (current logged domain user) Squid requests again me credentials ! While I type credentials of another domain user (different from my current domain user) surfing works ! Suggestions ?! It's very bizarre behaviour !
