I am running squid 2.5 using winbind authentication (with basic as a backup). It has been working great for close to a year now on both http and https sites.
Recently, we have run into problems with certain sites. These are sites that use https, but require the user to accept a PKI certificate before they can access the site. On the squid proxy with authentication, the user does not get prompted to accept the certificate and gets a connection failure message. The entries in access.log are 407 errors which I normally see on a failed authentication. Using the same computer and browser, I can point to another squid proxy that does not use authentication and I get prompted for the certificate just fine. I can point to a netscape proxy (no authentication) and it works. Any ideas on why squid with authenitcation is not able to connect to these sites? Brian
