function SystemDceSecurityProvider::getWindowsUid

Returns the user identifier for a user on a Windows system

Windows does not have the same concept as an effective POSIX UID for the running script. Instead, each user is uniquely identified by an SID (security identifier). The SID includes three 32-bit unsigned integers that make up a unique domain identifier, followed by an RID (relative identifier) that we will use as the UID. The primary caveat is that this UID may not be unique to the system, since it is, instead, unique to the domain.
