I found this to work with openvpn via the network manager: I don't know if the message is directly telling you this (it doesn't seem to), but it turns out that for some reason the Network Settings doesn't save your password. Look in /etc/NetworkManager/system- connections/ for a file that matches the name you gave your vpn in the settings. In my case it was just called 'client'. Open it as root in an editor.
sudo emacs /etc/NetworkManager/system-connections/client Then change this line in the [vpn] section: password-flags=1 to password-flags=0 Then add this section. [vpn-secrets] password="your-password" Where "your-password" is your vpn password. The quotation marks around your password are required.
