After having setup our CacheRefresh and authentication successfully with everything working, I followed the instructions in documentation for enabling CAS support. I followed every step but then (after chroot environment service restart of course) when I proceed to our "https://url.website.tld/idp/profile/cas/login" page, I'm confronted with an error: "ServiceNotSpecified" Figuring this may have something to do with Shibboleth, I searched their support / documentation as well as yours and found nothing. Please see the attached screenshot. I appreciate any and all help!  (Before anybody asks, yes I am forced to use CAS unfortunately.)
