Thanks Alan for your answer
I follow your documentation and succeed with the part "Configuring FreeRADIUS to use ntlm_auth"
So I want to use "Configuring FreeRADIUS to use ntlm_auth for MS-CHAP", so I delete my user in database.
Do I have to keep the following line in my radiusd.conf ?
exec ntlm_auth {
wait = no
program = "/path/to/ntlm_auth ntlm_auth --request-nt-key
--domain=MYDOMAIN --username=%{mschap:User-Name}
--password=%{User-Password}"
}
authenticate {
...
ntlm_auth
...
}

But I don't understand how to use a test client to send an MS-CHAP
authentication request ?
It's seem that i don't have a Auth-Type ?

Delete that row from the database.
The documentation tries to make it clear: Setting Auth-Type is wrong.
Don't do it.
