logons work if the client gives the MSV1_0_ALLOW_SERVER_TRUST_ACCOUNT or MSV1_0_ALLOW_WORKSTATION_TRUST_ACCOUNT flags. This changes the auth module interface to 2 (from 1). The effect of this is that clients can access resources as a machine account if they set these flags. This is the same as Windows (think of a VPN where the vpn client authenticates itself to a VPN server using machine account credentials - the vpn server checks that the machine password was valid by performing a machine account check with the PDC in the same was as it would a user account check. I may add in a restriction (parameter) to allow this behaviour to be turned off (as it was previously). That may be on by default. Andrew Bartlett please review this change carefully. Jeremy.
