[Samba] ntlm_auth and PEAP machine authentication

Thanks. I wish I could be of more help. The weird thing is that every once
in a while (like 1 out of 20 times) I get a successful machine auth via
ntlm_auth. It fails with either an incorrect password or unknown username
all of the other times.

Machine accounts are a problem because historically, they were not
permitted to login with NTLMSSP. This appears to have changed, but
there must be some flag that windows domain members set, to change this
behaviour. I don't know what this is at this stage, so I either need to
see this done to a windows DC, by a windows VPN server (with a system
policy of 'secure channel: sign'), or try random things till it works...
