I have a Jboss AS 4.0.3 cluster that has about half a dozen fairly large apps running on it that are all using SSO. I'm considering adding JBoss Portal to my cluster to be used as an entry point for my users, where I might have a collection of portlets that will provide a nice consolidated view of my applications.
The JBoss Portal user guide says that it supports SSO, but isn't clear as to how deeply SSO is supported. Can the JBoss Portal participate in SSO with the rest of my applications? In other words, can a user log into the portal, click on a link in a portlet to one of my applications, and then have their credentials available in my application?
