Hi,
You will need to have the MAC OSX join the active directory domain so it can have the proper machine credentials. If joining the macbook to Active Directory is not a viable solution then having a certificate issued to the macbook would be another option but you would have to user a user certificate.
If we take a step back, why are you looking to perform machine authentication for a macbook?

You will need to use a lion server to build a profile based on the instructions above.
