I'm sorry to tell that this does not work. Even if I give "staff" & "everyone" Read and Write access, I still get the same message: Access Denied.
When I start an Apple-app, OSX asks me to give this privilege to use folders and drives, but it forgets to ask me to give this privilege from a device that I as administrator want to connect to my own machine, even after explicit allowance to all items in my home directory.
Again: Why is Apple doing this? I want to use this on my local home network behind a firewall. I am not talking about sharing from obscure open networks in weird countries.
