Creating a VPN connection that requires just a client certificate allows the username/password to remain empty. But trying to connect to the VPN makes the login window to appear. Accepting the window without entering any credentials makes the VPN to connect successfully.
Ideally, there could be a config option to let the user decide if the connection will require credentials (and therefore, ask for them) or not (and therefore simply not asking for them).
