[libreswan] should save even when group name is empty.
GroupName (aka leftid
) could be empty which means in Main Mode
not Aggressive Mode
, so users shouldn't be prevented to save connection even when GroupName is empty.

In NetworkManager-libreswan client
section:
Note that until very recently (February 2016), NetworkManager only supported using Aggressive Mode and the Group Name field could not be left empty. If you see this happening, please upgrade your NetworkManager-libreswan (or NetworkManager-openswan) plugin.
