Yes, that's what I meant by connecting to port 18120.

When you run freeradius -X, the debug starts with the copyright notice at
the top. You don't have to worry about passwords being exposed, because in
newer versions you'll see "<<< secret >>>" instead of the real
password/client secret. :-)

This tends to help people like Alan and Arran when they're trying to help
you.

Yes, looking at some of the output:

> [ldap_1] looking for check items in directory...
> [ldap_1] sambaNtPassword -> NT-Password ==
> 0x3344424445363937443731363930413736393230344245423132323833363738

> "{MD5}ICy5YqxZB1uWSwcVLSNLcA=="

You receive NT-Password and LM-Password back, as well as
Password-With-Header with a '{MD5}' header in it. PAP will deal with that
password... Include 'pap' in the authorize section *after* ldap_1, then in
the authenticate section add the PAP type back in:

Auth-Type PAP {
        Pap
}

Try it then. If you're adding this into the inner-tunnel, make sure you
tell radtest to connect to localhost:18120.
