The Open Web SSO project provides core identity services to facilitate the implementation of transparent single sign on as an infrastructure security component. Targeted towards the web tier, this project provides the foundation for achieving seamless integration of diverse web applications that typically operate against a disparate set of identity repositories and are hosted on a variety of platforms such as web and application servers. This project is based on the code base of Sun Java(tm) System Access Manager product, a core identity infrastructure product offered by Sun Microsystems.
