package com.sun.security.auth;

 This class extends NTSid
and represents one of the groups to which a Windows NT user belongs.
 Principals such as this NTSidGroupPrincipal
may be associated with a particular Subject
to augment that Subject with an additional
identity.  Refer to the Subject class for more information
on how to achieve this.  Authorization decisions can then be based upon
the Principals associated with a Subject.
