I don’t know enough to address. The OAuth core spec currently says: The client MUST validate the authorization server's TLS certificate in accordance with its requirements for server identity authentication. RFC 2818 has guidance about endpoint identity, in Section 3.1: http://tools.ietf.org/html/rfc2818#section-3.1 RFC 6125 attempts to generalize the guidance from RFC 2818 and many similar specs for use by new application protocols. Given that OAuth as defined by the core spec runs over HTTP, I think referencing RFC 2818 would make sense. So something like: The client MUST validate the authorization server's TLS certificate in accordance with the rules for server identity authentication provided in Section 3.1 of [RFC2818].
