Hi,I have squid 3.1 installed using ldap authentication. When i access a browser i enter my ldap credentials and it works fine. I’m able to browse all sites without any issues.Is there a way to use ldap groups to allow certain groups access to a few sites on the internet and then pretty much block everything else?I’m able to restrict access to only a couple of sites and block everything else without using ldap group authentication, was just hoping this can be done with ldap group authentication.Thanks,Nando
