Feature Request - meaningful errors for access attempts on folders where the user is blocked

Hi,

I’ve got NextCloud running for a small NGO. I’ve implemented some access blocks to folders using flow rules and I’ve noticed that the errors given to blocked users on the desktop client (Mac) aren’t very informative. It would be useful to have a message that says ā€œAccess to this folder is restrictedā€ in the desktop client rather than ā€˜an unknown error occurred’ when attempting to look in/save to a blocked folder.

Cheers,

Spike
