Single Sign On Using JBoss User Portlet

[jaredmladner]

Hi,

I'm using Jboss Portal 2.2. I am also using JBoss's built in User Portlet to handle my login. If a user signs onto one machine then to another, I want to invalidate the first session. Reason being, I'm using a Singleton to pass information between multiple portlets.
Does anyone know how to implement Single sign on to the JBoss User Portlet?

Thanks, Jared

What do you mean by "machine" ? Are you running a cluster ? Single Sign On is about sharing authentification accross multiple web apps.
