Hi For every HTTPS-Site I have the following tcp_denied/407-entry in the access.log: 282895826.492 1 xx.xx.xx.xx TCP_DENIED/407 3720 CONNECT mail.google.com:443 - NONE/- text/html 1282896033.320 1 xx.xx.xx.xx TCP_DENIED/407 3744 CONNECT secure-www.novell.com:443 - NONE/- text/html The sites, which are denied in the access.log, are though accessible, but I have this errors. For me it seems, that squid needs a user authentication. But this should be given with kerberos-authentication, which works fine. I have the following directives configured (as default): acl SSL_ports port 443 acl CONNECT method CONNECT http_access deny CONNECT !SSL_ports Can someone explain me this behaviour? Thanks a lot. Tom
