I've been through all the steps on that and I get an Access-Accept when running the radtest against MSCHAP at the end, however when I connect from a supplicant I'm still seeing the following in the debug output.

Full debug output from radiusd -X is needed otherwise we're all guessing what's up. Have you got 'eap' configured in your inner tunnel (sites-enabled/inner-tunnel, likely)? When you're using a supplicant, you'll be doing EAP, which means that you need eap in both the outer and the inner - the inner eap then internally calls mschap to then call ntlm_auth. I'm guessing you followed all of Alan's web page, including the section at the bottom about configuring ntlm_auth in the mschap module (not the 'exec mschap' bit) - the ntlm_auth in mschap is essential for EAP-MSCHAP to work, whereas plain mschap (or TTLS/MS-CHAP) uses the exec variant.
The only thing in my users file is: DEFAULT EAP-Message !* "", Auth-Type := Accept
OK I misread - I thought you'd said it was working, and then stopped, not that it wasn't working to begin with...
This was a pre-packaged setup of freeradius, I've not knowingly put MS-CHAP-Use-NTLM-Auth = Yes somewhere, although I will look around and see what I can find.
Don't bother, if you've never added it - it shouldn't be there. Matthew

My freeradius server seems to be falling back to local authentication rather than piping it out to our ADS server. If I create a local user on the radius box authentication is successful. Can anyone please help with this? All relevant info I can think of is below.
Initial guess - you've set MS-CHAP-Use-NTLM-Auth = Yes somewhere (check for broken entries in your users file, etc), so mschap isn't even trying to call ntlm_auth.
