Accounts and Identities

Nishant Kaushik makes a very good point in his latest post on the Virtual Directory vs AD debate:

Here is my point. Martin says “AD is the directory…”. I say that “AD is a directory…”, and that too because Windows forced it on those enterprises, not because of their Identity Management needs. Yes, almost all the Fortune 500 have AD, but are they using it as an Identity Store, or as a Windows Account Store (which is very different)?

To answer the rhetorical question, the vast majority of AD deployments are not intended as identity stores (at least from my experience). In most enterprises AD is used to manage and control user access to Windows workstations, the intranet, email, and enterprise web applications. AD is not usually intended as a central repository of identity, although it often becomes that with varying degrees of success.

And here is the real crux of the matter: most enterprises don’t really want an identity solution. What they want is a “spend less money, get everyone access to what they need when they need it, keep the bad guys out, keep us out of the headlines, and the CEO would  really, really, like not to go to jail” solution.

They have been, in many cases, sold on the idea that identity management is the solution that they want. And indeed it can be part of the solution.

But here is the brutal truth, and the reason that enterprise identity management is so messy. Almost all enterprise applications are account-based not identity based. Very few products support externalizing the identity concept in their products. They most you will usually see is supporting AD or another LDAP for authentication. Less often you might see simple group membership for authorization. A few commendable vendors such as SAP support SAML, but it’s a very small list. Support for external identity services or other identity standards such as SPML and XACML is nearly  non-existent.

Which ties in with the question Nishant closes with:

By the way, why is it that architectural purists don’t ask when Microsoft will make it possible for Windows environments to work against any directory and not just AD, but Oracle Applications must support directories other than OID? In the end, both Microsoft and Oracle are wrong to push proprietary stores into deployments, contributing to the mess we have.

  1. I think you hit it right on the head when you pointed out the crux of the problem. Unitl there is an understanding of what IdM can do for the enterprise as an enabler rather than as a catchall we’ll see the true paradigm shift.
