   I cannot reproduce this, and I have no idea what your server-side utility shows.
   
   Run your test program with debug logging on and examine the client log. You will see that it will send an initial `SSH_MSG_USERAUTH_REQUEST` for authentication method "none". The server will reply with a failure, and will tell in that failure reply the client which authentication schemes are enabled on the server. Then the client will choose keyboard-interactive and send the real authentication request SSH_MSG_USERAUTH_REQUEST for "keyboard-interactive" with the password.
   
   As far as I can tell everything is working exactly as it should. Maybe teach that server-side utility not to report SSH_MSG_USERAUTH_REQUEST "none". See [RFC 4252, section 5.2](https://www.rfc-editor.org/rfc/rfc4252#section-5.2).
