#### Configuring Mutual Authentication

In mutual authentication, both server and client-side authentication are enabled. To test mutual authentication, a client with a valid certificate must exist. For information on mutual authentication, see the Security section of the http://java.sun.com/javaee/5/docs/tutorial/doc/index.html.

To enable mutual authentication for a specific application, in the deployment descriptor, set the method of authentication to `Client-Certificate`. For more information about using `deploytool`, refer to the Security section of the Java EE 5 Tutorial.
