SPAuthnContextMapper Parameters

The following query parameters can be set in the URL when accessing spSSOInit.jsp:

• AuthnContextClassRef or AuthnContextDeclRef: These properties specify one or more URI references identifying the provider's supported authentication context classes. If a value is not specified, the default is urn:oasis:names:tc:SAML:2.0:ac:classes:PasswordProtectedTransport.

• AuthLevel: This parameter specifies the authentication level of the authentication context being used for authentication.

• AuthComparison: This parameter specifies the method of comparison used to evaluate the requested context classes or statements. Accepted values include:

  • exact where the authentication context statement in the assertion must be the exact match of, at least, one of the authentication contexts specified.

  • minimum where the authentication context statement in the assertion must be, at least, as strong (as deemed by the identity provider) one of the authentication contexts specified.

  • maximum where the authentication context statement in the assertion must be no stronger than any of the authentication contexts specified.

  • better where the authentication context statement in the assertion must be stronger than any of the authentication contexts specified.

  If the element is not specified, the default value is exact.
