First of all, it looks like your Apache Virtual Host is configured for port 80. See the section of the error where it says "Constructing validation url: https://cas.id-dev.ubc.ca...";? That "https://"; means it's going to connect to the CAS server via SSL (by default to port 443), and since Apache is presumably only listening on port 80, no connection can be made ("Connection refused").
Do some reading on the how and why of setting up SSL with Apache. (A few google searches should get you on track.) SSL is a "must-have" with CAS servers. -- You are currently subscribed to [email protected] as: [email protected] To unsubscribe, change settings or access archives, see http://www.ja-sig.org/wiki/display/JSG/cas-user
