Can't copy folders - only individual files.

[jonpage0]

When copying individual files or deleting them I have no issues. When I try to copy any folder I get the error:

The operation can’t be completed because you don’t have permission to access some of the items.

I've checked permissions on both the Ubuntu server and my Mac. Everything appears to be setup correctly. I'm not sure what else to try and diagnose as I've never encountered this kind of issue before.
