Abstract

An intermediary server operates an application proxy. An access request is received for access to an application, where an access policy is associated with the application that specifies authentication method(s) acceptable for satisfying an authentication requirement enforced by the application proxy. The user agent is redirected to submit an authentication request to an identity provider for identity verification. An authentication response generated by the identity provider is received and includes information that specifies authentication method(s) used during the identity verification. If the authentication method(s) used during the identity verification match the authentication method(s) acceptable for satisfying the authentication requirement, the user will not be prompted to perform those authentication method(s) and the authentication requirement enforced by the application proxy is met. If they do not match, the user will be prompted to perform the authentication method(s) as a condition to access the application.
