Thanks! Are you able to do a wintest with this?

I also want to do some tests with windows dcs.

I important thing I want to verify is the behavior of

+       domain->conn.netlogon_force_reauth = true;

in _wbint_CheckMachineAccount() and related code.

Testing against a s4 dc showed that we are doing
netr_ServerReqChallenge/netr_ServerAuthenticate3 over a connection
sure Windows also likes that.

I think some combination of 'wbinfo -t' and 'wbinfo -c' triggered that.

Günther can you also do some tests with your VMs?
