## Interface JMXAuthenticator

-     public interface JMXAuthenticator

  Interface to define how remote credentials are converted into a JAAS Subject. This interface is used by the RMI Connector Server, and can be used by other connector servers.

  The user-defined authenticator instance is passed to the connector server in the environment map as the value of the attribute `JMXConnectorServer.AUTHENTICATOR`. For connector servers that use only this authentication system, if this attribute is not present or its value is `null` then no user authentication will be performed and full access to the methods exported by the `MBeanServerConnection` object will be allowed.

  If authentication is successful then an authenticated `subject` filled in with its associated `principals` is returned. Authorization checks will be then performed based on the given set of principals.

  Since:
    1.5
