Dave, Perhaps my terminology was incorrect. I am wanting Squid to log/filter web traffic. I want permissions to be based on A/D security groups. >From what I read, using NTLM or Samba, I could do this... The proxy works fine, although it is requiring a login when a user opens an IE session and I don't want the user to be prompted for username and password. Instead, I'd like Windows to pass the credentials automatically. Like I noted, though, it would appear it is passing only the username and not the domain\username... It occurred to me that this could have been the reason for the login every time someone opens IE. Any suggestions or ideas? Thanks.

What are you trying to accomplish? Dave
