in the first instance, you will need to decide how you are taking to
LDAP - either looking things up (oracle) or binding to LDAP use the
user , either way will give you some restrictions as to what you can
and cant do

in the second instance , its not doing EAP because radtest is not an
EAP testing tool - you need to use eg eapol_test (from the
wpa_supplicant package) or other tool to test EAP on the command line
(which I would strongly suggest you do before bringing in real traffic
from Access Points and clients.....
