Hi,

i've a problem similar. But i stored my password in LDAP database in clear
mode. So, i don't understand why it doesn't work too.

Passwords are not crypted !!!

the error is :

rlm_mschap: No User-Password configured. Cannot create LM-Password.
rlm_mschap: No User-Password configured. Cannot create NT-Password.
rlm_mschap: Told to do MS-CHAPv2 for example with NT-Password
rlm_mschap: FAILED: No NT/LM-Password. Cannot perform authentication.
rlm_mschap: FAILED: MS-CHAP2-Response is incorrect
modcall[authenticate]: module "mschap" returns reject for request 6
