Cannot access directories over SMB (permissions error)

Question

I am unable to access directories like ~/Documents, ~/Downloads, or ~/Desktop via SMB — the SB share on which they exist can be accessed, but not the directories themselves (trying to browse them gives permissions errors)

In Console.app, I have (for kernel), e.g.,

System Policy: smbd(7706) deny(1) file-read-data /Users/alex/Documents

This appears when I try to access ~/Documents.

How can I fix this so ~/Documents and similar dirs are accessible via SMB?

In the Privacy tab of the Security & Privacy system preference pane, make sure that either:

1. smbd appears and is checked in the Full Disk Access list, or
2. smbd appears with Documents Folder checked below it in the Files and Folders list.

If you need to add smbd, it can be found in /usr/sbin.
