#eic10 part 1, 2010 an interstellar odyssey -or- the directory monolith

No one knows how to make a big proclamation in the identity world like Kim Cameron. His keynote at #eic10, the Kuppinger Cole European Identity Conference for 2010, was no disappointment. Kim reviewed his ideas for the “Federated Interscaler Directory”, which was often misquoted as saying “Interstellar”. The basic idea was to “extend” the current ubiquitous Active Directory platform to hold a more flexible framework for relationship expression, policy enforcement and other elements that directories of today are missing. While adding all that, this new directory platform should also scale, in the sense that it could administer millions of identities, as well as support advanced features like federation, token translation and other things that are clearly becoming part of next gen identity.

On it’s surface, that all sounds nice. But it also sounds dangerous to me. One other theme at #eic10 throughout many talks, and something Kim even said during his, was that we shouldn’t want identity systems to be monolithic (he said so in reference to the ability to federate with other IdP’s outside the directory itself). But the system Kim described and the picture he used to illustrate it looked pretty monolithic to me. A lot of what he described is possible today already with a loose federation of platforms from many vendors and open source projects. You can enforce all the policy you need with a XACML authorization engine and properly tooled interfaces and proxies for applications and providers. You can manipulate schemas and the objects they serve up as needed with virtual directories. If Microsoft were to make AD into one big solution for all that, then the biggest differentiator would be having its monolithic status versus the loose coupling of many other components. I tend to be a fan of loose couplings, but I’ll keep the jury out until I see more from Kim.

One thing that I really liked was Kim’s call for everyone to work together on a common identity schema. It’s not the first time he’s done so. At PDC he made a great presentation that described the same idea in much greater detail [link to the PPTX Powerpoint file from PDC]. A project of this kind, if well done, could solve many, many interoperability and operational challenges in the identity world. So much time is spent now negotiating, either in research or in calls at run time, to figure out what attributes and properties of an identity are available. If there were a completely standard schema and a means to publish it easily, then that goes away.

I’ll have more thoughts from the conference later.  For now I’m going to put on my space suit and leave the Microsoft ship and hope Kim hasn’t locked the bay doors when I get back.
