With a preview of his forthcoming book from O'Reilly Media, Phil Windley joins The Gang to share his insights on digital identity. The result is an excellent Digital Identity 101 by Professor Windley. Phil explains the differences between virtual directories, metadirectories, centralized directories and federated identity. Other topics include Shibboleth, role-based authentication, SAML, the Liberty Alliance, and SXIP. Also, what's the potential role of DNS in identity management, who controls identity (users or vendors), and who will be the winners and losers in the identity-management game?
