      @function SessionSetDistinguishedUser
      This function allows the creator of a (new) security session to associate an arbitrary
      UNIX user identity (uid) with the session. This uid can be retrieved with
      SessionGetDistinguishedUser by anyone who knows the session's id, and may also
      be used by the system for identification (but not authentication) purposes.
      
      This call can only be made by the process that created the session, and only
      once.
      
      This is a private API, and is subject to change.
      
      @param session (input) Session-id for which to set the uid. Can be one of the
        special constants defined in AuthSession.h.
      @param user (input) The uid to set.
