You might check out this thread:
<https://www.centos.org/forums/viewtopic.php?t=8626> Scroll to the bottom,
where they solve it - they've got the ifcfg-wlan0. Also - I haven't done
this in years - you might rpm -ql wpa-supplicant; I'd be surprised if they
didn't have, maybe /usr/share/wpa-supplicant? anyway, a sample
ifcfg-wlan0.
