It’s now April 2006. The above specs are implemented in various commercial and open-source products (e.g. SAMLv2.0 conformance-tested products).
What’s up with deployment? Various people have claimed that “those
specs are too complicated and aren’t user-centric, and there isn’t any
wide deployment of them” (to sort of paraphrase, but nearly quote).
The good news is that I will moderate a panel at the next WWW conference (afternoon) on this very topic: a reality check about identity management.
