43 List of tasks vampire.py must perform:
44 - Domain Join
45 - but don't write the secrets.ldb
46 - results for this should be enough to handle the provision
47 - if vampire method is samsync
48 - Provision using these results
49 - do we still want to support this NT4 technology?
50 - Start samsync with libnet code
51 - provision in the callback
52 - Write out the secrets database, using the code from libnet_Join
