To Whomever It May Concern, I have been poking around the Internet and mailing lists and anything else I can think of, for DAYS, to try to answer what I thought would be a simple question, "How can I configure Squid so that my authorized Windows users (Members of the proper security group in AD who are logged into the network) don't have to answer a challenge to get out to the Internet?" That answer, as it turns out, is not obvious - at least, not anywhere I've found to look. Lou Lohman Linux Evangelist Weber Marking Systems Arlington Heights, IL -- "90% of the game is half mental."
