I run a java client with use the ClientLoginModule to transfer credentials to the JBoss server. The client acces a protected method(test) on a stateless session bean running in the "other" default JBOSS security domain.
This is the client:

 public static void main(String[] args) {
 try {
 SecurityUtil sc = new SecurityUtil();
 char[] passw = {'d', 'r'};
 sc.login("dragos", passw);
 SecurityServiceDelegate securityDelegate = new SecurityServiceDelegate();
 securityDelegate.test();
 sc.logout();
 } catch(Exception e) {
 System.out.println(e.toString());
 }
 }

i have users.properties and roles.properties in <JBOOS_HOME>/server/default/conf

users.properties:
--------------------
dragos=dr
cristi=cr
user1=u1

roles.properties:
-------------------
cristi=user
dragos=user
user1=user

But when the client run I obtain this error:

rdcs.core.client.DelegateException: java.rmi.ServerException: RemoteException occurred in server thread; nested exception is:
java.rmi.ServerException: EJBException:; nested exception is:
javax.ejb.EJBException: checkSecurityAssociation; CausedByException is:
Authentication exception, principal=dragos

on the client side and

on the server side

where is the mistake?
As far as I see the principal 'dragos' is transfered to the server side but there I encountered an authentication exception
