Class NullAuthentication

java.lang.Object
  wt.auth.NullAuthentication

All Implemented Interfaces:

AuthenticationHandler

public class NullAuthentication

extends Object

implements AuthenticationHandler

Authentication (or lack thereof) based on trusting the user name supplied by the client. The client can assert the user name through a call to RemoteMethodServer.setUserName. If the user name is not set the client's user.name Java system property is used. This authentication scheme is only supported for stand-alone applications running on the server's local host or a host identified in the server's wt.auth.trustedHosts property.

Supported API: true
Extendable: false
