it *should* work :)

could you please provide part from /var/log/messages, where 
nut-{driver,server} are being started? Also what systemd and nut version 
do you have (together with release number) ? rpm -q nut systemd

There is one bug in systemd, that breaks driver-server relation:
https://bugzilla.redhat.com/show_bug.cgi?id=704197, it was fixed 
recently, but it's still not available as update.
