 This class extends NTSid
and represents a Windows NT user's primary group SID.
 Principals such as this NTSidPrimaryGroupPrincipal
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.
