This class implements the Principal interface and represents a Windows NT user. 
 Principals such as this NTUserPrincipal 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.
