The server will, by default, continually check that the clients
328
316
are still up. If a client has not been confirmed as being up

331
intervention is required to re-enable a client.) The timeout,

The server can be configured to require manual approval for a

approval and the default action (approve or deny) can be

This can be used to deny a client its secret if not manually

optional manual denying of this specific client.
