[cas-user] CAS Authentication failed with Clustered Moodle

[Tillinghast, Andrew P.]

We've been reliably running a single server moodle instance with CAS enabled for over a year.  Recently we've moved to a cluster of Moodle servers and sporadically users are seeing a "CAS Authentication failed!" message. At first I thought the error must be session related so I've verified the following settings. Cluster is managed with a Cisco ACE 4710 and the sessions are sticky. Both moodle sessions and php sessions are written to a shared NFS space.  Does anyone have a suggestion on how we can address this issue?
