I have a user share named "tmp," but it isn't being exported via Samba. After the change, it is mounted at /user/disk1/tmp. That's why I'm wondering myself why setting the settings to "Array" instead of "Cache" affects its behavior. (Share Settings/Primary Storage) The original error message mentioned access problems to /tmp in the Samba VFS. And I don’t think this was referring to my user share. So unfortunately, I can’t explain to you in more detail why it’s working now....
