Thanks for the reply Andy. Yes jboss portal and other popular portals should support a way of supplying/customising user attributes but my question is about jboss portlet container which, out of box, doesn't seem to have clear instruction of how to do it. We're basically implementing a portal using the portlet container plus our own code for identity, group and layout management because of the migration need from our previous portal.
