Hello, Last few days when I looked in to access.log and report using lightsquid. I found usage report of some users are error. Report of user1 showing websites those he never accessed to and it came from user2. I don't know what could be the cause but I have tried restart both Squid server and AD but report still the same. I'm now using Squid 2.6 on CentOS box with 'winbind' for authentication. Please advice what should I do to fix this problem. Thank you. Mo.
