H.6.2 PLUGIN_INIT_RESPONSE

Direction: plugin to client

When: response to PLUGIN_INIT

What happens next: the client will send PLUGIN_PROTOCOL, or perhaps terminate the session (if no auth method is ever negotiated that the plugin can help with)

Message contents after the type code:

• uint32: the version number of this protocol that the connection will use. Must be no greater than the max version number sent by the client in PLUGIN_INIT.
• string: the username that the plugin suggests the client use. An empty string means that the plugin has no opinion and the client should stick with the username it already had (or prompt the user, if it had none).
