I think I see that I do not have an authentication backend 
configured.  /etc/freeradius/modules/smbpasswd exists, but it isn't called by 
anything.

I found a commented authorisation method "smb_passwd" 
in /etc/freeradius/sites-enabled/default and uncommented it.  This fails, the 
module is actually "smbpasswd", changed that, still fails.  It appears to be 
using username DOMAIN/user, which of course doesn't exist in the smbpasswd 
file, so I tried configuring the client to do just username, as the old 
server seemed to be failing to parse the domain and using NULL.

Different error:

This _looks_ like it succeeds, but the connection is not established because 
it didn't actually do CHAP:
