AuthenticationProxy (apache-cassandra API)

java.lang.Object
- org.apache.cassandra.auth.jmx.AuthenticationProxy

All Implemented Interfaces:

javax.management.remote.JMXAuthenticator
```
public final class AuthenticationProxy
extends java.lang.Object
implements javax.management.remote.JMXAuthenticator
```
An alternative to the JAAS based implementation of JMXAuthenticator provided by the JDK (JMXPluggableAuthenticator). Authentication is performed via delegation to a LoginModule. The JAAS login config is specified by passing its identifier in a custom system property: cassandra.jmx.remote.login.config The location of the JAAS configuration file containing that config is specified in the standard way, using the java.security.auth.login.config system property. If authentication is successful then a Subject containing one or more Principals is returned. This Subject may then be used during authorization if a JMX authorization is enabled.
