| 34 | * <p> Windows NT chooses to represent users, groups and realms (or domains) | ||
| 35 | * with not only common names, but also relatively unique numbers. These | ||
| 36 | * numbers are called Security IDentifiers, or SIDs. Windows NT | ||
| 37 | * also provides services that render these SIDs into string forms. | ||
| 38 | * This class represents these string forms. | ||

| 41 | * may be associated with a particular <code>Subject</code> | ||
| 42 | * to augment that <code>Subject</code> with an additional | ||
| 43 | * identity. Refer to the <code>Subject</code> class for more information | ||
| 44 | * on how to achieve this. Authorization decisions can then be based upon | ||
