Synopsis

The value of uPortal is often articulated in terms of aggregation of user attributes, group information, and user preferences, driving a customized user experience via sophisticated layout technology and mediated by a permissions engine. Guest pages are often little more than an exhortation to log in and enter the richer authenticated user experience. This presentation will challenge that viewpoint on uPortal, examining the potential for leveraging uPortal to provide rich, customized user experiences from the "zeroth click", the very first portal HTTP response. Examples will be speciifc to the technologies of JA-SIG projects uPortal and CAS, but the ideas are applicable for other portals and authentication mechanisms.
