Turns out is triggered by NetworkManager-openvpn stripping the "comp-lzo no" option from the imported .ovpn config file, misrepresenting a 3-value option as a simple check box, and giving the user no way to enter the correct setting.
Checking the "Use LZO data compression" box in the Advanced... config dialog *might* work around the problem. This does not map to the intended "comp-lzo no" setting in openvpn, but if the server is pushing the setting to the client, it might work anyway. More details in the upstream bug report. ** Summary changed: - auth_failed when attempting openvpn via networkmanager + NetworkManager-openvpn mishandles the comp-lzo option, thereby breaking the ovpn config and causing AUTH_FAILED -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1661098 Title: NetworkManager-openvpn mishandles the comp-lzo option, thereby breaking the ovpn config and causing AUTH_FAILED To manage notifications about this bug go to: https://bugs.launchpad.net/network-manager-openvpn/+bug/1661098/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
