Squid logging issues

I finally got denied websites and ntlm group-based authentication working on the squid server at work, but it seems that it (still) doesn't log usernames in the access.log (which also has to be explicitly defined in squid.conf to be able to log for some reason...

I have tried allot of Google searches for it but there's nothing relevant that I can find, so I think this is either an undocumented 2.6 bug or I am not looking properly for any possible userid logging bugs.

This sure is beginning to bug me.

Maybe I have missed something...
