Hi all! I have the following config for Squid2.6STABLE4: https_port webmail:443 cert=/usr/local/etc/squid/certs/webmail.foo.com.pem defaultsite=webmail.foo.com protocol=http vhost cache_peer x.x.x.x parent 80 0 no-query originserver front-end-https proxy-only cache_peer_domain x.x.x.x webmail.foo.com acl Websites type accelerated acl Website_domains dstdomain webmail.foo.com http_access allow Websites Website_domains http_access deny Websites The problem is that is can't authenticate with my Exchange Server. When I get the login dialog from my Exchange Server and enter the *right* credentials I get an access denied after 3 tries. Do I have a config problem here??? Next to this I also get a certificate error in my browser claiming that the cerfiticate could not be verified properly. I have a valid VeriSign signed certificate for this website .... can this be a problem of IE 7?? TIA Bert.
