re-authenticating with Duo; this allows connections from particularly flakey networks to reconnect seemlessly without user interactions; NOTE: this explicitly circumvents the authentication mechanism! Only use this if you know what you are doing!
…cation plugin here; (instead, use 'hand-window' or beware of buggy openvpn bailing on reneg-sec 0)
A 'composite' password is one that combines a single password string for multiple authentication plugins, for example ldap authentication and duo. 'Composite' passwords are formed by combining two passwords with a comma, ie "<ldap>,<duo>". This commit thus generates two distinct modules, allowing the user to choose either one in the openvpn configuration.
