freeradius-1.1.1 + mschap + ldap with encrypted password

[wekz <fbl.list@gmail.com>]

Hi all, 



I've configured freeradius-1.1.1 to do eap-tls and peap to authenticate windows wireless users against an ldap.

The problem now is that I have to authenticate doing peap against an ldap which has userpassword encrypted ( and is a point that I can't change unless it is impossible to do ). I know that when I'm using peap what I finally use is mschapv2 and  that this protocol makes a challenge ( with username, password and somestuff ) that the user must response. As my ldap-user-passwords are encrypted and microsoft clients make the response with a clear-test password, it couldn't work. At least that's what I've understood ( and my knowledge about this is very limited, so correct me if I'm wrong ).  My question is if there is anyway to make it work configuring ntlm_auth ?

Thanks in advance.
