Windows LiveID

We commented on an post from Phil earlier in the year on this very subject

http://www.mwdadvisors.com/blog/2005/10/loosely-coupled-reinvents-passport.html

Your references to Passport are interesting in light of this white paper from Microsoft discussion Passport 2.0 aka Windows LiveID: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnlive/html/winliveidserv.asp

which includes the following:

Microsoft has published its vision of a universal identity solution that is inclusive of a plurality of identity operators and technologies?the identity metasystem. In such a metasystem, identity providers, relying parties, and subjects can select, request, transfer, transform, and consume identities through a suite of well-defined and open Web Services (WS-*) protocols. Microsoft is working to implement components of the identity metasystem, as are many other companies in the industry. As a result, various building blocks for the metasystem are being developed. Some of these components will be delivered to end users in the form of software installed and running locally on their computers and devices, while others will be online services.

The design philosophy of the identity metasystem is not to replace the existing identity systems in use today, but instead to bring these existing systems together by enabling interoperation among subjects, relying parties, and identity providers through industry standard protocols. The Windows Live ID service will participate in the identity metasystem as a "managed" identity provider already at Internet scale. Windows Live ID will bring a large base of end users and relying parties to the metasystem, taking us one step closer to Internet-wide identity federation and doing our part to help the industry move beyond the "walled garden" paradigm.

The Windows Live ID service will play several essential roles that are strategic for Microsoft. The service:

* Is an Internet-scale identity provider intended primarily for users of Microsoft online services, which are all relying parties of the Windows Live ID service.
* Is open and issues claims in a form that can be consumed by any relying party, any device, and any other trusted identity authority.
* Serves Microsoft online services as a "claims transformer," allowing those services to accept identities issued by third-parties. Third-party identity providers include other Internet service providers and managed-identity providers, such as the planned Active Directory Security Token Service (STS).
* Will be the identity provider and federating authority for third party services and software built on top of the Microsoft online services platform.
