annotate listener.h @ 1534:ed930fd6f60f

Added the -G option to allow logins only for users that are members of a certain group. This allows finer control of an instance on who can and cannot login over a certain instance (e.g. password and not key). Needs double-checking and ensuring it meets platform requirements.
