libnetconf2 seems to handle keyboard-interactive authentication incorrectly, as it responds with a spurious SSH_MSG_USERAUTH_FAILURE when asked for keyboard-interactive authentication.
This results in handshake state error, with the an extra SSH_MSG_USERAUTH_FAILURE being delivered to an authenticated session. While OpenSSH reacts with SSH_MSG_UNIMPLEMENTED, Apache MINA SSHD throws an IllegalStateException and terminates the session.
