AWESOME it is working mostly flawlessly!! I notice that the whitelist file (/etc/squid3/whitelist1.sites) doesn't take comments or duplications or reduntant info. Like .ftp.debian.org when there is already a .debian.org. It errors and don't work. But once I got over that it seems to be working nicely. As long as you surf the white list you aren't prompted for a password. But if you go off white list you are!! Is it possible to direct browsers that fail to authenticate to a website? I could direct them to the internal web server with instructions on how to get valid credentials.
