Identity is a rapidly evolving field. From WS-Federation, CardSpace, and SAML to OAuth and OpenID, the identity landscape has been in considerable flux over the last few years. There are many identity providers competing to represent your users, such as Google Accounts, Windows Live ID, and Facebook Connect. Add to that mix intermediaries like JanRain's RPX and the Microsoft Federation Gateway, and mix in the various APIs you can use in your code, and things can get really confusing, really fast. This talk will help you sort out identity technologies, giving you ideas as to where they might fit in your web application, and how you can protect yourself from the churn that will invariably come in the next few years.
This session is presented by Keith Brown during Microsoft DevDays 2010 in The Hague in The Netherlands.
