4.6.2.1 RP Allowlists of IdPs

RPs MAY establish allowlists of IdPs from which the RP will accept authentication and attributes without a runtime decision from the subscriber to use the IdP. In practice, many RPs interface with only a single IdP, and this IdP is allowlisted as the only possible entry for that RP. When placing an IdP in its allowlist, the RP SHALL confirm that the IdP abides by the terms of the trust agreement. This confirmation can be facilitated by a federation authority or undertaken directly by the RP.

RP allowlists SHALL uniquely identify IdPs through fully qualified domain names, cryptographic keys, or other identifiers that are applicable to the federation protocol in use. Allowlists SHOULD be as specific as possible to avoid unintentional impersonation of an IdP. An allowlist entry for an IdP SHALL NOT use a wildcard domain identifier.

RP allowlist entries MAY be applied based on aspects of the federation transaction, such as the xALs required for the transaction. For example, an RP could use a runtime decision for FAL1 transactions but require an allowlisted IdP for FAL3 transactions.
