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