IFWXAuthenticationCompletion interface

Applies to: desktop apps only

The IFWXAuthenticationCompletion interface includes a method for receiving an authentication completion notification and information associated with the authentication process.

When to implement

An application filter that calls the IFWXRadiusAuthenticator::AuthenticateRadiusUser method to perform RADIUS authentication must implement this notification interface.


The IFWXAuthenticationCompletion interface inherits from the IUnknown interface. IFWXAuthenticationCompletion also has these types of members:

  • Methods


The IFWXAuthenticationCompletion interface has these methods.

Method Description

Receives a notification that an asynchronous authentication operation initiated by a call to IFWXRadiusAuthenticator::AuthenticateRadiusUser has completed, and receives information associated with the authentication process.



A filter can use the IFWXFirewall2::CreateRadiusAuthenticator method to create a new IFWXRadiusAuthenticator interface and obtain a pointer to it. When a request is received on a listener that has RADIUS authentication enabled, and the filter requires RADIUS authentication, it calls IFWXRadiusAuthenticator::AuthenticateRadiusUser and supplies a pointer to an IFWXAuthenticationCompletion notification interface.
