ntlm_auth

[Jonathan Hutchins]

Looking carefully through the log, I saw that I had disabled mppe when I was 
testing without the domain (?).  Renabled it.

Gentlemen, we have a working configuration!  I can ping severs on the network 
over the VPN.

So I'll reiterate some of the wisdom you've shared with me:
Start with a clean config.
Make small changes and RECORD EVERY CHANGE. then test by running freeradius -X
Read the FAQ and other docs.
Post the output of the debug run.


Thibault, can I write any of this up to add to the PopTop howto?

Finally, a log from the working server.  Any recommendations on cleanup or 
improvement appreciated.
