When you initially deploy Unified Access Gateway, Active Directory password authentication is set up as the default. Users enter their Active Directory user name and password and these credentials are sent through to a back-end system for authentication.
You can configure the Unified Access Gateway service to perform Certificate/Smart Card authentication, RSA SecurID authentication, RADIUS authentication, and RSA Adaptive Authentication.
Note: Only one of the two factor user authentication methods can be specified for an Edge Service. This can be Certificate/Smart Card authentication, RADIUS authentication, or RSA Adaptive Authentication.
Note: Password authentication with Active Directory is the only authentication method that can be used with an AirWatch deployment.
