Thank you.  FWIW, quoting the page was more me was trying to figure it out;
it wasn't intended to offend.
Your comments made me realize that freeradius is (to all intents and
purposes) working properly, and that the problem lies with the ldap host.
I'll need to figure that last bit out (your a and b above).  It should be
interesting with FreeIPA, which is notable for not making access to the
NTHash passwords simple.
