Enterprise technology for the real world.
The ongoing collaboration between Microsoft and Sun Microsystems delivered a very significant step forward in the business goal of Web services interoperability to bridge the real gaps between customers' IT systems.
At a joint press conference, Steve Balmer and Scott McNealy announced details of two new specifications to enable browser-based Web single sign-on across domains between Liberty Identity Federation and WS-Federation.
It's all done by leveraging the existing WS-MetadataExchange protocol framework.
Web Single Sign-On Interoperability Profile
Web Single Sign-On Interoperability Profile defines an interoperability profile of the Web Single Sign-On Metadata Exchange Protocol that allows using either Liberty Identity Federation or WS-Federation-based Identity Providers to interact with a service.
Web Single Sign-On Metadata Exchange Protocol
Web Single Sign-On Metadata Exchange Protocol defines how a service can query an identity provider for metadata that describes the identity-processing protocol suites supported by that provider.
These specs will go through the same WS-* Workshops Process that we use for all the other WS-* specs.
At the same press conference, Sun also announced they will be implementing WS-Management in its x64 Opteron servers, N1 management products, and Solaris 10.
