Hi Marc, if, as you say, you need to remove everything before 
reprovisioning, why are there these lines in the provisioning code 
(/samba/provision/__init__.py):

  def provision(logger, session_info, smbconf=None,

     """Provision samba4

     :note: caution, this wipes all existing data!
     """

And:

def setup_samdb_partitions(samdb_path, logger, lp, session_info,

     """Setup the partitions for the SAM database.

     Alternatively, provision() may call this, and then populate the 
database.

     :note: This will wipe the Sam Database!

     :note: This function always removes the local SAM LDB file. The erase
         parameter controls whether to erase the existing data, which
         may not be stored locally but in LDAP.

If I have to reprovision, I just remove smb.conf and I have never had a 
problem.
