David Chappel è una delle persone più chiare e brillanti che conosco. Microsoft gli ha chiesto di fare un whitepaper sui vari aspetti e i vari prodotti utilizzati per affrontare "il problema dell'Identità"
Identity is an inescapable aspect of distributed applications. The .NET world provides several technologies that developers can use in this area, but figuring out what each one does and how they fit together can be challenging. ...Available here, the technologies it describes include ADFS, Windows Cardspace, and several more.
Handling identity well should be a fundamental competence for anybody who creates .NET applications. The goal of this paper is to help people get started on the path to acquiring this competence.
