thomasjojo, those issues will not really be resolved.
The tasks you try to do, copying, deleting, renaming, all require the "x" (execute) privileges on that filesystem. Which you can't get on SMB from the *X platforms such as OS X. You can get read and write (RW) and improve those, but X is just utopia - unfortunately. With any method you currently have for accessing, using, reading, writing, doing anything from a Mac on those systems will all have RW but not RWX.
