Additional Notes

The http://schemas.microsoft.com/claims/authnmethodsreferences claim is only supported in the specific case of Microsoft AD FS and Azure AD identity providers; in all other circumstances it is filtered out.

Where authnmethodsreferences includes a specific reference to the REFEDS MFA profile of https://refeds.org/profile/mfa, the corresponding <samlp:AuthnContextClassRef> element will be set to match. This allows IdPs to explicitly signal their MFA is compatible with REFEDS MFA.

It is also possible for the Federation hub to translate a authnmethodsreferences claim asserting Microsoft’s multi-factor authentication method (http://schemas.microsoft.com/claims/multipleauthn) into a corresponding <samlp:AuthnContextClassRef> element asserting the REFEDS MFA profile of https://refeds.org/profile/mfa. However, because not all multi-factor authentication methods supported by Microsoft are compatible with REFEDS MFA, this quirk is not enabled by default.

Identity providers that wish to make use of REFEDS MFA and require this quirk must explicitly request it, and confirm that the multi-factor authentication methods they use are compatible with REFEDS MFA.

For this quirk to work with AD FS, the IdP must assert at least one other authnmethodsreferences attribute value corresponding to the factor actually used. Some known-incompatible methods are automatically filtered (e.g. http://schemas.microsoft.com/ws/2012/12/authmethod/email), and only the remainder are considered.
