Specify how unregistered RPs can use OpenID Connect

[jsmarr]

10. Unregistered RPs

• RPs should not have to pre-register to use OIC
• Unregistered client support already in OIC Proposal
• Unregistered client support will need to be defined to support OAuth2 for IMAP/SASL (in progress)

Merging two of these:
6) IdP Discovery

Much of this will be covered by OAuth2 Discovery, however OIC may need to define OpenID specific features.

Sadly "OAuth 2.0 Discovery" hasn't materialized. Hopefully what we define for Connect will be usable by the OAuth community.
