Hi,

as it says

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 myRfx 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 9

you will need a clear-text password or a NT/LM password hash to be in your
LDAP directory. Then you have to map that attribute ( for example
sambaNTPassword ) to User-Password. You are trying to do MSCHAP but there is
simply no defined password for this authorization type.

Regards,

Edvin

Subject: 802.1x ldap tls

Hi list,

yes I know that this question has been discussed so many times but, 
still I'm in trouble.

I've set up freeradius in order to authenticate+authorize Cisco NAS of
Aironet.

I've successfully connected PC/MAC wireless clients using TTLS+PAP 
with in backend and LDAP DB.

Problem arise when I try to make the same with TLS, I mean 
PEAP+MSCHAP and LDAP DB. THis doesn't works. If I set a local user in 
users file, that is good, but if I try a LDAP user nothing come.

LDAP store plain password. Some hints ?

Here, some extracts from log:
