My proablem is "No User-Password or CHAP-Password attribute in the request" message it is clear but my supplicant (XP and SecureW2) don't
sent User-Password as is seen :

User-Password not in request. How am i sent User-Password ?
I tried WinXP 802.1x (EAP-MD5) and SecureW2(EAP-MD5).
My /etc/users file is following :
---------------------------------
DEFAULT Auth-Type = LDAP
        Fall-Through = 1
---------------------------------

Thanks your relation.
