[Samba] Reverse (negate) veto directive

[Mark Clarkson]

Does anyone know of a way to reverse the effects of the "veto files"
directive in smb.conf?

My situation is that I have a share that I only want to have *.pdf files
created in the share.  I tried this:

  veto files = /*.*/!*.pdf/

but that did not work.

Does anyone have any ideas or know if this type of thing can be
accomplished?

Thank you
