Hi all,

We want to start a migration from JBoss 5 applications to JBoss 6, and in the meantime we want to keep serving what we already have.

We have JBoss 5 in domain mode clustered in a bunch of servers with instances in each one.

The idea is to create a brand new JBoss 6 cluster (domain mode too) and put there migrated applications.

How can we provide single sign on between both clusters? is it possible to do it?

The scenario will be just like:

• jboss5.mycluster.com
• jboss6.mycluster.com

The service is available at jboss5.mycluster.com. It contains a menu and a frame that loads content based on menu options. So, when the user picks an already migrated app, it should load the content in the frame (or the worst case, would be redirected to jboss6.mycluster.com).

What do you thing of this approach and what tool do you recommend for doing SSO between both clusters?

Best,
Sebastian
