/*
 * Security Identifier (SID)
 *
 * The security identifier (SID) uniquely identifies a user, group or
 * a domain. It consists of a revision number, the identifier authority,
 * and a list of sub-authorities. The revision number is currently 1.
 * The identifier authority identifies which system issued the SID. The
 * sub-authorities of a domain SID uniquely identify a domain. A user
 * or group SID consists of a domain SID with the user or group id
 * appended. The user or group id (also known as a relative id (RID)
 * uniquely identifies a user within a domain. A user or group SID
 * uniquely identifies a user or group across all domains. The SidType
 * values identify the various types of SID.
