Identity is Totally Forked Federated identity has diverged Enterprise-centric User-centric Nothing matters but users and applications Is divergence desirable, feasible, neither? “When you come to a fork in the road, take it” – Yogi Berra

Enterprise-Centric Federated Identity Enterprise asserts identity data on behalf of an individual for which it is authoritative Attributes Identity Trust relationships and integrated applications defined by the enterprise Federations SAML is the primary protocol

Students, Identity, and School Services how many email accounts do they have that parents don't know about- do they use same password 4 all #socialmedia ? #teens “ They don't use email so it's more a matter of which ones they forgot about. They often forget their passwords so I would guess that they don't use the same password consistently. Of course, they also share certain passwords with their closest "trusted" friends so that gets messy really fast. And they change it when there's a breakup.” Do they really care about/use school library websites? “ Nope, they don't. All but Twitter [which they don’t use] are categorized as school tools and are only used when absolutely necessary and Google won't suffice.” http://www.zephoria.org/thoughts/archives/2009/05/16/answers_to_ques.html

Ne’er the two shall meet?

Protocols World’s most ridiculous fight But there’s bad blood and high stakes Most protocols can solve most problems Hacks, revisions, kludges Identity sources should support many protocols and apps should be agnostic Deployed base is large
