Class Challenger

com.sas.services.security.Challenger

All Implemented Interfaces:

RemoteCallbackHandler, java.io.Serializable, java.rmi.Remote, javax.security.auth.callback.CallbackHandler

public class Challenger
implements RemoteCallbackHandler

The Challenger class helps bridge the non-remote JAAS callback classes with the remote PFS versions of the callbacks. This allows clients to handle the standard callbacks, but still work across a a remote interface. A class which implements the javax.security.auth.callback.CallbackHandler interface instantiates a new Challenger passing a pointer to itself as a parameter (typically), then passes the new Challenger instance to UserService.setChallengeCallbackHandler().
