No, will not work. You can't transform the normally used hashes back
into a cleartext password. (This is kind of the whole point of a hash.)

As long you don't have any means to provide FreeRADIUS with a cleartext
password or the NT/LM-Hash, you are doomed.

ntlm_auth just offloads the whole Challenge-Response exchange from the
RADIUS server to the ActiveDirectory (as far as I understand it) using
the ntlm_auth binary from Samba. Again: the AD will have to know the
cleartext password in some way (either encrypted or somehow
"pre-hashed") to make this work. (Don't know the specifics, I am a Unix
guy, the only Windows near me is on my gaming computer.)


Sigmentation fault. Core dumped.
