Simple answer: SARG (or any log analyzer) requires Squid to post usernames in the access log, by using authentication helpers. I am not certain if this can be done in Transparent or Intercept mode at all. >>> chinner999 <chinner999@xxxxxxxxx> 7/20/2011 12:11 PM >>> Hi guys, I have SARG running and the reports shows usage per user by ip address. How do I get it to show username instead? The users are using Active Directory. I don't have Squid configured for any authentication currently. Ubuntu v10.04 Sarg v2.2.7.1 Squid v3.1.6 - transparent Thanks.
