Correction. There are a few confusing terms here. 'transparent' means different things when used to describe HTTP proxy actions and Active Directory authentication. *transparent interception* (the proxy term) and the way HTTP works prevents regular HTTP authentication methods being done. That is an absolute. Security feature in browser. etc. etc. *transparent* authentication (the AD term people seem to like. I assume they really mean invisible to the user) is one of the non-HTTP authentication methods that can under careful setup work. Amos > Yes you can.
