Today, the Liberty Alliance announced the latest results in their interoperability conformance testing program where, to date, almost 75 products/solutions have achieved interoperability with other implementations.
This is important for people inside and outside of Liberty because it means that when you look to implement federated identity solutions, products from different vendors on the list will be much more likely to interoperate. Intel's first attempts to implement federation solutions (BMT - before my time) ran into several issues related to interoperability failures that would have surfaced in such testing. Had the products been through this conformance program, that would have made life much simpler for everyone.
Congratulations to the new (and old) products that have made it through the program!
