NetworkManager’s OpenVPN plugin problems on Ubuntu

After trying to connect to OpenVPN using NetworkManager on Ubuntu 10.04 LTS (Lucid Lynx) I got an error:

The VPN connection “XXX” failed because there were no valid VPN secrets

Nothing seemed to help, but after some google’ing I have found a fix that worked for me:

1. Edit /etc/dbus-1/system.d/nm-openvpn-service.conf and add additional policy:

<policy user="at_console">
    <allow own="org.freedesktop.NetworkManager.vpnc"/>
    <allow send_destination="org.freedesktop.NetworkManager.vpnc"/>
</policy>

2. Restart the NetworkManager after the new policy is added: sudo /etc/init.d/network-manager restart

After these steps the VPN started to work.
