My changes make everything work. I got CAS working (with the help of Webnard) we have created a node-"ful" and Beautiful engine to get and authenticate tickets from CAS. It has been said that these changes have been so beautiful they have made grown men cry. Yes I mean men over the age of 16.
I'd recommend doing this with a configuration file. Or as Ian has mentioned, you could also use environment variables.
