# Class NTSidDomainPrincipal

java.lang.Object
com.sun.security.auth.NTSid
com.sun.security.auth.NTSidDomainPrincipal

All Implemented Interfaces:
  `Serializable`, `Principal`

public class NTSidDomainPrincipal extends NTSid
This class extends `NTSid` and represents a Windows NT user's domain SID.

An NT user only has a domain SID if in fact they are logged into an NT domain. If the user is logged into a workgroup or just a standalone configuration, they will NOT have a domain SID.

Principals such as this `NTSidDomainPrincipal` 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`.
