Scenario: uPortal is not able to obtain password from CAS, CAS has java.net.SocketTimeoutException: Read timed out

This can be caused by one of the following:

• In filters/*.properties and how the cas clearpass property is specified in security.properties, CAS is making an HTTP call to uPortal to send the PGTIOU-PGT message.
• In uPortal ehcache.xml, RMI cache replication is setup for clustered uPortal configuration but the RMI server list in filters/*.properties lists a server that is not accessible so RMI replication of the PGTIOU-PGT message holds up a response to CAS and CAS times out.
