Hi there, I'm trying to setup a Squid 3.3.8 on a Ubuntu 14.04 and I'm having some problems with the NTLM authentication. We have three ports, 2 are with authentication (3128 and 3129). The server is joined to a Windows 2008 domain and authentication works fine on machines that are also in this domain. But on non-domain machines, in Internet Explorer I get the authentication popup up to 6 times, then I get "Access denied" and only after a reload, the site is viewed correctly. With our old Squid 2.7 I just had to login once. I tried to adapt our existing 2.7-config for squid3, maybe I made a mistake, can someone help me to fix this error? Or is this a smb/winbind related error?
