Hello, I'm currently satisfied with my round-robin DNS enabled "cluster" of two Squid with ntlm authentication. But, with th appearance of Windows 7 and Windows 2008, I see by searching for documentation on the web that I need to use Kerberos Authentication if I would like Internet Explorer 8 from 2008 or 7 to work. Do you have any advices for achieving this setup ? What clustering mechanism do you use. Does the kerberos part of the install need to be customized to support being put in cluster mode (which needs to be defined) ? Thanks for your helps and docs. PS : Testing it will be easy so I thinks I'll enable Debian Backports repository in order to have 2.7STABLE9. -- Emmanuel Lesouef
