Public bug reported: I have nm-openvpn configured via the network manager gui on Xenial with a saved password. My organization has a password expiration policy of X days. If I forgot to update the saved password for nm-openvpn and try to VPN in, nm-openvpn tries the connection, fails without notice in the UI and retries until I stop it. This ultimately causes my account to get locked out for too many invalid auth attempts.
