.  A mainstream website might trust any IDP who is hosted by a known SaaS vendor.  However for the longer-tail we may see a need for companies who build a business out of validating the UI/reliability of IDPs and selling those lists to other websites.


This seems very SAML-notion centric, based on architectural forms ~5 years old.

Isn't the ___user___ supposed to be in charge, in OpenID?

Isn't that the CRUX of what openid is all about  and what makes it different to SAML (other than needing SSL/PKI and using name/value pairs and XRDS markup ...instead of the SAML markup and xmldsig?)

OpenID is not an idp-centric federation concept . OpenID is not an sp-centric federation concept. It CLAIMS/CLAIMED to be a user-centric (federation) concept - a model seekingto differentiate itself from the well-known hangups of the previous 2 concepts.



I have  to admit, from the trends I see, and in the hands of the "big players": OpenID is turning into a simple lightweight version of SAML2, featuring the idp-centric model. If one uses the unsolicited assertion model, it does do a damn good impression of SAML1, too.

I have to admit I don't think we in realty, could really care less. But, what was always interesting/revolutionary about openid was the model, not the swap of bits. If OpenID is just a lightweight SAML, all I need to do is stick a protocol gateway on the front of the SAML endpoints we already have, and be done with it.
