If you delegate EAP-SIM authentication to RADIUS, you won't need the
eap-sim plugins on the server. Further, a client never needs the
eap-radius plugin; it does not directly speak RADIUS.

Seems that the plugin can't find your RADIUS configuration in

You should not explicitly define a load statement. ./configure your
installation with what you need, and let the daemon handle plugin order
and the plugin list.

At a first look your gateway strongswan.conf is fine. Please double
check that you are editing the same file as the daemon reads (your
--sysconfdir= matches your strongswan.conf path), and access rights are
ok. Given that your explicit load statement does not throw a warning,
I'd guess that the daemon does not read from the correct file.
