[Catalyst] Catalyst authentication w/ CAS

[Baron Fujimoto]

Hmm, I have now (sorry, didn't occur to me to look there). If I create a
new skeleton app using that, it kicks out to our CAS server as expected,
but after authenticating there I end up in the if( $c->authenticate )
else block with Access Denied. So I have two things to sort out now: 1)
find the difference between the example app below and mine that allows it
to successfully call CAS, and 2) determine why $c->authenticate is being
evaluated as false.

Aloha,
