network-manager-openvpn lacking support for pkcs12
--
network-manager-openvpn: cannot import connection from ovpn file
Actually I found how to convert my pkcs12 file using info from this Bug
#91615 and everything works fine.
I really think though that support should be added for pkcs12 files, as
numerous other reports indicate (e.g. Bug #287603)
I guess you can close the bug report...
