Oh... and why did you not use domain authentication? It should be easily doable in squid...
I must have posted at the same time as you. I didn't use domain authentication at the time of setting it up because I have clients with different versions of windows servers and different client operating systems and also because of the complexity of integrating the active directory user accounts with the filtering system. Also it does not work with ipads, cell phones etc.
But a new feature has come out in the program that I am using where you can use different proxy port numbers for different users. Same proxy, just a different port number. So I will be moving to this as proxy authentication is a pain in the arse!
