I'm running blades that run jboss-eap-4.3 with mod_jk load balancing the servers.

I'm using JAAS for authentication and I'd like to be able to authenticate on the primary server and have that authentication propagate to the other jboss instance if one of the servers goes down and jk moves the user to the other server.
I have configured clustering with TCP and both blades seem to see each other in the cluster.

The issue I'm seeing now is that when I authenticate sucessfully I can do what I need to do. When I kill that jboss instance, I'm properly routed to the other app server by mod_jk, but I have to re-log into the app.

Can anyone give me any hints as to how to make this work.

Thanks!
