    winbindd: trigger possible passdb_dsdb initialisation
    
    If the passdb backend is passdb_dsdb the domain SID comes from dsdb, not
    from secrets.tdb. As we use the domain SID in various places, we must
    ensure the domain SID is migrated from dsdb to secrets.tdb before
    get_global_sam_sid() is called the first time.
    
    The migration is done as part of the passdb_dsdb initialisation, calling
    pdb_get_domain_info() triggers it.
