Hello, First: I'm an intern and know little of pretty much everything. Try to explain the best you can, please! I'm trying to set up Kerberos on a Squid proxy server (the server is to allow access to ip-based content away from the intranet, so it will be something like so: client --> internet --> VPN --> access to intranet --> proxy server --> ip-based content). Unfortunately, every time I connect to the proxy to connect to random webpage, I receive the error "Cache Access Denied". According to the guy who manages the Kerberos stuff around here, the machine is authenticated with Keberos and has a ticket...so apparently it's something to do with Squid (but don't necessarily rule out Keberos...he may be wrong)? I set-up Squid using Kerberos (note that prior to the Kerberos installation, Squid worked fine)doing exactly what was stated in this guide: http://klaubert.wordpress.com/2008/01/09/squid-kerberos-authentication-and-ldap-authorization-in-active-directory/. The "Kerberos guy" did the Windows step for me...so there shouldn't be any problems there. As it says in the guide, I did compile Squid with basic authentication....but I didn't set it up whatsoever and haven't changed any settings relating to it...could this be the culprit, perhaps? This actually seems somewhat likely to me because the error occurs when I run squid with the start-up script (that includes the line: export KRB5_KTNAME=/etc/squid/squid.domain.keytab) and when I start squid using the sbin file...(so it shouldn't even be loading the keytab file here). I know this information see
