5) Backwards compatibility

  • Existing implementers of OpenID 2.0 must be able to provide a seamless upgrade path for existing users. Existing OpenID 2.0 userids should be returned via OIC assertions, so that RPs do not need to authenticate returning users twice to link legacy OpenID 2.0 identifiers with new identifiers.
  • user/realm specific checkid_immediate settings - existing OpenID 2.0 users who have enabled checkid_immediate for their account for a particular realm should have that preference automatically honored for OIC requests.
  • realm specific PPIDs should be automatically migrated to OIC

This is a great topic for the summit!
