NTSystem for Administrators only (on NT4)

Question

One more time this problem appears in the forum.
Perhaps someone will answer this time.
Simple application :
public class TestNTUser {
public static void main(String[] args) {
System.out.println((new com.sun.security.auth.module.NTSystem()).getName());
This works fine for a user in the Administrators local group.
This produce the following error for a user in the Users local group.
Simple error :
javax.security.auth.login.LoginException: OpenPolicy failed
     at com.sun.security.auth.module.NTSystem.getCurrent(Native Method)
     at com.sun.security.auth.module.NTSystem.<init>(NTSystem.java:50)
     at TestNTUser.main(TestNTUser.java:4)
Exception in thread "main"
