Working with CAS 7 and login with RC8 is failing (was working in earlier RC versions) Error thrown:
https://pastebin.com/8xsf1yFc
This occurs before the login page, looks like it's blocking the login webflow. From the error I suspect there is some required property value related to encryption that we are missing.
If it might be related we are acccessing CAS vis http/8080 as we are off-loading the SSL to an appliance.
