Ticket 49015 - register-ds-admin.pl - silent install does not
        register local instances
    
    Bug Description:  There is no way to specify how to register local instances with
                      a local configuration server when using silent install.
    
    Fix Description:  Revise the [register] directive section to allow "local instances".
