Peap et freeradius

Bonjour.
je realise une authentification radius
sous linux (mandrake 10.0) et mes clients sont sous windows xp

l'authentification eap-tls fonctionne mais je n'arrive pas a faire fonctionner peap
J'ai configuré le client (mschapv2) et le serveur en peap mais je recois l'erreur suivante
je me demande si le probleme ne vient d'un mot de passe non recue car c'est ecrit
no User-Password attribute

or dans mon fichier users, voici mon utilisateur
clienrad User-Password == "azertyui"
j'ai donc bien un attribut password
