I first heard of CAS two days ago and decided to try it out.
I'm working with a guy who has a CAS version 2 server.
My web server is Apache 2.2.3 on a clone of Red Hat Enterprise 5.
I found an RPM for mod_auth_cas 1.0.7 and installed it with no
problem. I made a minimal setup: I set CASLoginURL, CASValidateURL
and CASDebug on. Everything else was left alone. I made a directory
and put the directives
AuthName "CAS"
AuthType CAS
require valid-user
in its configuration.
When I direct my browser to that directory, it is redirected to the
CAS server's login page. After entering my username and password,
I am sent back to my destination, with
?ticket=ST-2217-Bj9j9WvqzXqa2arzgZE5 appended to the URL. So far
this looks good.
Unfortunately the result is a 401 error, "Authorization Required".
I boosted Apache's LogLevel to "debug" and got this:
