treat "auth" setting case-insensitive
NetworkManager treats the auth setting case-sensitive. Hence, setting
auth sha1
is going to fail with "Invalid HMAC auth."
It seems that the auth parameter is treated case-insensitive. Hence, importing a .ovpn file from https://www.privateinternetaccess.com/pages/client-support/fedora-openvpn results in a non-functioning configuration in NetworkManager.
- Investigate + confirm that the auth paramter is truly case-insensitive
- adjust the plugin
