Bryan, It looks like mod_auth_cas is not configured to handle SAML 1.1 service tickets or the page that cas redirects to is protected (which then goes back to cas instead of processing the ST).

We are using mod_auth_cas on a RHEL 7 server. mod_auth_cas is working with some other entities, on this server, just fine. With this one entity, however, we run into problems. Our application correctly redirects to their CAS login page, for authentication. But after successful authentication, we get one of two results, in the browser: In Firefox: we get a blank page -- still on THEIR CAS server page. In Chrome: We get a 500 server error -- still on their CAS server page. The Apache error log, on our side, shows a bunch of stuff happening behind the scenes, however, and it looks to me like something is looping. The URLs get longer and longer until it quits processing. I'll attach the error log, showing one authentication request. (I've replaced their domain name in the log file with # characters. Does anybody have any idea what might be going on here?
