Okay I have squid running V. 2.5.STABLE9 using msnt_auth works great however I want to know if there is a way I can use NT Groups to lock down users access I have groups for every department and some of them dont need access to the internet I am having problems with wb_ntlmauth and ntlm_auth that I cant seem to get around so If there is a way to do it with msnt_auth I would like to please advise Brian
