3.1.1.2.2.2.7 String(Sid)
A value with this syntax contains a SID in binary form. The binary form is that of a SID structure (the SID structure is specified in [MS-DTYP] section 2.4.2.2; all multibyte fields have little-endian byte ordering). It is otherwise encoded the same as the String(Octet) syntax.
