As of Monday morning I have an OVM management server that is refusing to authenticate any user. Nobody admits to have changed anything on the server over the weekend. The server is fully patched using the public Oracle yum server. The oc4j log file regularly (every 15 minutes) prints out an error message that's maybe 400 lines long.
Here's the tail end of the oc4j log file:
