4.6.2.2 RP Blocklists of IdPs

RPs MAY establish blocklists of IdPs from which the RP will not accept authentication or attributes, even when requested by the subscriber. A blocklisted IdP can otherwise be in a valid trust agreement with the RP, such as when both are under the same federation authority.

RP blocklists SHALL uniquely identify IdPs through fully qualified domain names, cryptographic keys, or other identifiers that are applicable to the federation protocol in use. Any entities that share an identifier SHALL be considered equivalent for the purposes of the blocklist. For example, a wildcard domain identifier of “*.example.com” would match the domains “www.example.com”, “service.example.com”, and “unknown.example.com” equally. All three of these sites would be blocked by the same blocklist entry.
