I am currently testing a PHP script found at PHP Classes web site named SASL. I am going against a Squid Proxy Server. No matter what I enter for a userid and password it comes back with a response of 200. I assume this means that I hit the Squid server NOT that authentication passed. So how can I tell if authentication failed or was a success? Is there a var set somewhere? REMOTE_USER is not being set. Help is greatly appreciated. TIA. Mike
