package javax.management.remote;

import java.security.Principal;
import javax.security.auth.Subject;


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

Authenticates the MBeanServerConnection client
with the given client credentials.


Params:
  • credentials – the user-defined credentials to be passed
into the server in order to authenticate the user before
creating the MBeanServerConnection.  The actual
type of this parameter, and whether it can be null, depends on

with the provided credentials.
Returns:the authenticated subject containing its associated principals.
