Hello Stefan,

It would make sense to only apply to directories.
And yes, that is how it should work according to my understanding as 
well, however I lack the insight into the SAMBA code base to have an 
idea on how to cleanly implement that transition.  I would appreciate 
any ideas you or others may have on how to get there.

Thanks!
