Cliff,

 

Stupid question: what version of CAS are you configuring?

 

I examined the source behind the ticket granting ticket expiration class
and noticed it always references the system time, so even if it was
skewed, it wouldn't affect things.  Perhaps Scott can comment whether a
clock skew affects anything in CAS.

Andrew,

 

How important is it for the server's clocks to be in sync?  I have been
playing around with NTP.  I am not sure that I have gotten it right,
yet.  But, the clustering seems to be working.

 

Cliff

Clifford,

 

You are correct, JBoss Cache is to replicate CAS' ticket registry.  This
ticket registry along with Tomcat's session information must be
replicated amongst all of the clustered machines.  Excuse the obligatory
"did you" checklist:

 

*       Configured Tomcat's conf/server.xml for session replication
(different settings than JBoss)
*       Configured firewall to accept connections for both Tomcat and
JBoss session replication
*       Modified applicationContext for ticket uniqueness and configured
cas.properties file with servers' names

 

If you could, configure Log4J to log debug messages for
org.jasig.cas.ticket.registry and org.apache.catalina.cluster.  This
might tell you why Apache / JBoss hasn't found the other member.

The production environment has 4 Apache/Tomcat servers fronted by a
BigIP load balancer.

 

To test out the concept, I have 2 (virtual) Linux servers each running
Tomcat, with Apache load balancer on one of them.

 

I thought that the JBoss stuff was for the Ticket Cache Replication?

Clifford,

 

What is your intended scenario?  Have you setup two instances of CAS on
a single machine or are they on different machines?  It appears as
though you have JBoss configured for localhost (127.0.0.1:32789), which
makes me curious.

Hi,

 

I followed the instructions in the CAS clustering link.  The multicast
ping is working.  But, the CAS clustering is not working.  If I shut
down the first server, and browse to the second server, then I am
prompted to login again to the second server.

 

This is the log from Catalina.out.
