I am following this documentation to set up shibboleth authentication, and I am stuck where it states to do the Regex of <LocationMatch ^/[^webwork2_files|^webwork2_course_files]>. When I restart Apache, and click on the class I get an error stating authentication failed as shown below. When this happens it doesn't pass through to our 2FA system. To test if it is our 2FA system set up, I had also set up (and commented in/out) putting all of webwork behind shib via <Location /webwork2> and it works. Attached is also the current shib.conf file. Am I missing anything in my shib.conf file that is causing this?
