Thank you for your reply. We had our CAS clustered but ran into the issues discussed. We are trying to work through the problems and get the CAS cluster back up. Until we can do so, we have put our old login page in place, so currently we only have a few 3rd party applications (VERY minor hitters) using our CAS server, which is why we have no concern of only have one up right now. But before we turn all of our university's logins back to going through CAS we will definitely have it in a cluster. Your environment sounds very similar to what we had, it will be interesting to see what more testing brings. I appreciate you taking the time to help.
