Passport and Liberty: A Match Made in Heaven?
Single sign-on has long been the Holy Grail in identity management.These days, an increasing number of my friends are looking for Valentines online. Unfortunately, its all too common for people to pretend to be someone theyre not. Or at least, stretch the truth. Too often SWM with George Clooney looks, future CIO, turns out to be SWM with George Costanza looks and a help desk job. Identity problems, unfortunately, are even more complex in the world of enterprise computing. As Web services move from early adoption to mainstream acceptance and migrate outside of the safety of enterprise firewalls, an increasing number of organizations are faced with the task of ensuring users are who they say they are. On top of that, these enterprises are also working to authenticate users not just for one application, but a slew of them. Single sign-on has long been the Holy Grail in identity management. The ability to eliminate the need for users to manually enter a different username and password to gain access to applicationsor, in the case of consumers, e-commerce sites--would not only lower help desk requests but also provide a more rewarding user experience.
But to date, single sign on implementations have been few and far between. The main culprit: The lack of interoperability between proprietary technologies from different vendors.
