Freeradius and Active directory

[Tomáš Janeček]

MYNTDOMAIN is just a fake Domain name I pasted in the log. But ntlm_auth 
on server uses my real domain...

I see the error announced by ntlm_auth, but don't know how to repair it. 
When I run ntlm_auth --request-nt-key --domain=MYREALNTDOMAIN 
--username=user and provide the password, everything works fine...

The Windows machine is member of domain (for few months).

Isn't there a problem with the PLAINTEXT?
