thank you Alan
(i am on the FAQ)

user=maman
passwd= maman
is a sql based user.

trying peap with sql based user give error message, but trying it with Ad_based user give no error message, just don't connect...

with radtest:

radtest maman maman localhost 1812 testing123
Sending Access-Request of id 48 to 127.0.0.1 port 1812
        User-Name = "maman"

        NAS-Port = 1812
rad_recv: Access-Accept packet from host 127.0.0.1 port 1812, id=48, length=20



same credential with my Access-Point (part of output).
