Does that mean that I don't need to use the LDAP modules on FreeRadius and use only the ntlm_auth? Is is enough?

Because Active Directory isn't LDAP in the same way that other LDAP servers are LDAP. You can't get NT-Passwords from AD, you can get it from other LDAP servers. Therefore, you can't get FreeRADIUS to compare a known good password to the password in the Access-Request, you've got to use something else. In this case, NT domain authentication does MS-CHAP, so FreeRADIUS can use ntlm_auth to do MS-CHAP to the NT domain, and thus authenticate the user. Alan DeKok. - List info/subscribe/unsubscribe?
