I have never gotten machine authentication to work so have no idea what I'm talking about, but would that be necessary?

Unless you've written some samba config to change the behaviour, I believe ntlm_auth looks at the entire tree - ntlm_auth/libwbclient are happy to authenticate any valid user regardless of position in the tree.

The wiki mentions an interesting snippet of information - it suggests you might need to send "00" as the username:

I'd also look suspiciously at how the backslashes are being handled (packet capture and see what's really being put on the wire?), and the docs by nt_domain_hack in rlm_preprocess, which suggest you may need to mangle the username.
