4.A.1 MS-DTYP #
The SID type defined in this document derives from the Microsoft
Data Types specification (MS-DTYP), §2.4.2. The Peios binary
encoding is identical to the MS-DTYP packet representation, and the
string form follows the same S-R-I-S convention. The structure
itself originates in Windows NT, where it has been the principal
identity primitive since NT 3.1.
