Running Big Sur 11.5 and trying to use File Sharing to access my drive on my local network. I only wish to allow the primary user access so I set the permissions accordingly ("everyone" has no access).
However, after ~1 day (hard to figure out exactly when), the permissions will revert, allowing anyone read access which is the default setting. This occurs without rebooting, the only operations being connecting to the SMB share and waiting some amount of time.
Is there something I'm doing wrong with the configuration? I've looked into alternative network file sharing servers (even just
brew install samba) but can't find anything with good documentation besides the native SMB file sharing.
