Need some help. My college has up until now been running Squid 3 on Ubuntu 12.02 and now 14.04 successfully. That was till recently.

Our WSUS server is dishing out updates to all our workstations of which Internet Explorer 11 is one of them. Now all of a sudden users do not need to authenticate via the squid proxy to be able to use the internet. This makes it rather difficult as I also use SARG to generate usage logs for all users each day. All our workstations also have Chrome on them, and Chrome authenticates fine via the Squid proxy.

Doing a couple of Googles, I ran into and article, where someone made mention that Microsoft has deprecated digest and basic authentication from IE 11. Reason was given that Office 2013 was giving problems as it was not giving the popup screen for authentication when Office tries to download templates from the internet. I have run into this problem, but by setting those sites to not authenticate via squid fixed the problem.

Has anyone else run into something similiar? Would changing to NTLM or Kereberos be a solution?
