Good morning Squid Support, I've been setting up a replacement Squid proxy server.
After setting up the backend using realmD, sssd, with Kerberos authentication, I tested with a Windows "squidaduser" account. I can verify the user accounts connection to the proxy, and it is passing traffic. The issue is, it's not being blocked by ANY of the acl's we have in place. I was hoping to reach out to help me identify the issue with the squid.conf file. This is my assumption to be the issue but I am pretty new at using Linux and completely unfamiliar with setting up a web proxy.
