PAPE may be another approach (to support per-user per-RP login policies). It certainly will not always be “cleaner”. It is not a reason against enabling a discovery-based approach. This PAPE suggestion requires the RP and OP to implement what the user wants. A discovery-based approach only requ

James Henstridge, > why wouldn't this alternative [doing it all at the OP] be appropriate? It would be great if OPs offered lots of functionality (such as per-User per-RP policies), while remaining simple to use and understand. The great feature of OpenID is that is allows each user to choose l

I have a few more questions about the update_url feature of OpenID attribute exchange that I feel could do with answers in the specification. For the questions, imagine an OpenID RP with the following properties: 1. The RP provides a unified login/signup workflow, so that if a user signs in with

The User-Agent field does not have the right semantics. I hope that field could be used, for instance, to notice which Relying Parties are using a particular version of Janrain’s Java library for OpenID. It is probably reasonable for Bloglines, Google etc to identify themselves in the User-Agent
