After much fussing, I seem to have a working Squid 2.6 working against a Samba 3 PDC. My only question is now, can I say, ok, if you finds my username, give it complete access. Then perhaps, if it sees user, "bob" perhaps, then it says, only give them windowsupdate.microsoft.com. Then if it sees user "tony, perhaps, only give it, www.tony.com. Can I do all of these Internet limiting features?
