What Do You Mean, Identity 2.0?

Identity management means different things to different people—everything from passwords through pgp to marketing preferences. What are the essential elements of the Identity 2.0 movement, and why should a system administrator care about any of this in the first place?

This talk will discuss the current state of Identity 2.0, starting with a brief survey of identity management from AAA to the user-centric identity model of Identity 2.0. I will then use Jon Callas's breakdown of identity management types to categorize and describe how and why the average system administrator would implement Identity 2.0.
