com.sun.security.auth.NTSid

All Implemented Interfaces:

Serializable, Principal

Direct Known Subclasses:

NTSidDomainPrincipal, NTSidGroupPrincipal, NTSidPrimaryGroupPrincipal, NTSidUserPrincipal

public class NTSid
extends Object
implements Principal, Serializable

This class implements the Principal interface and represents information about a Windows NT user, group or realm.

Windows NT chooses to represent users, groups and realms (or domains) with not only common names, but also relatively unique numbers. These numbers are called Security IDentifiers, or SIDs. Windows NT also provides services that render these SIDs into string forms. This class represents these string forms.

Principals such as this NTSid 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.
