Well, it says you're trying to log in as user "Prof-PC\\Prof" amd
the login was incorrect.

You've chopped out all the useful debug, so I'll have to guess
that you're calling ntlm_auth, and that is the external script. In
which case, debug it by running ntlm_auth manually on the RADIUS
server to make sure that bit works, then start investigating what
comes from the client.

0xc000006d should mean the username or password isn't correct
(hence "logon failure").
