We are getting some Win7 machines so I am migrating our ntlm setup to Kerberos. Looking at Markus Moeller's kerb guide, I see that it doesn't state how to control access after successful auth. Looking online, http://klaubert.wordpress.com/2008/01/09/squid-kerberos-authentication-and-ldap-authorization-in-active-directory/ suggests an ldap companion method but this involves a patch. Is that patch still needed, or does there exist a stock approach to facilitate this, as our access is done by group ad membership? Thanks, jlc
