I would agree with that analysis based on the stack trace.  The
failure appears to happen when the CAS client attempts to connect to
CAS for service ticket validation.

You mentioned this could be related to SSL, but I've not seen this
sort of error caused by SSL trouble.  But I would agree that
investigating that a little deeper would be a good first step.  I
recommend you produce an SSL trace on the client application
(uPortal?).  Assuming you're running tomcat:

1. Create/edit a $TOMCAT_HOME/bin/setenv.sh with the following:
CATALINA_OPTS=$CATALINA_OPTS" -Djavax.net.debug=ssl"
export CATALINA_OPTS
2. Restart the container and attempt to reproduce the problem
3. Examine the file containing the contents of stdout (catalina.out by
default), which should contain the trace

Send the trace to the list if you need help reading/analyzing it.
