Hi Andrey, Ubuntu 11.04 Squid 3.3.10 (compiled natively on Ubuntu 11.04) AD Version: 5.2.3790.3959 (would not surprise me if this AD version is out of date) No SSL I am not really an M$ guy so I do not know a whole lot about the AD side of it except that I am finding it extremely difficult to integrate with Squid on linux ;-) I have Admin access to the AD server yet as I mentioned earlier it was useless in trying to help diagnose this problem! Thx for any help you can provide!
