I have a problem, I would like to get all my questions from the internal network to the internet over squid proxy, with using delegated authentication. (SQL,NTLM...). Is that possible? I know that the transparency function is not be able to authenticate. But what can i do? For example: Ipsec Connections, Openvpn connections and many other client programs used for internet connections over squid. And i have to log all the traffic with ip, username and password. sorry for this stupid question, but i want to learn.
