basically lock_path() is for CLEAR_IF_FIRST files,
cache_path() is on persistent storage but can safely deleted
by the admin. And state_path() is for real persistent data.
winbindd_cache.tdb is only in state_path() because of the
"winbind offline logon" option. otherwise is could be
in lock_path() as it's CLEAR_IF_FIRST.
