As the added commend and `man smb.conf` explain, starting with that samba version, `force user` must be configured in `[global]` in order to access the configured `smb_dir`.
This broke `-net user,smb=/path/to/folder`: The `chdir` into e.g. `/run/user/0/qemu-smb.DCZ8Y0` failed. In verbose logs, this manifested as: [..., effective(65534, 65534), real(65534, 0)] /source3/smbd/service.c:159(chdir_current_service) chdir (/run/user/0) failed, reason: Permission denied [..., effective(65534, 65534), real(65534, 0)] /source3/smbd/service.c:167(chdir_current_service) chdir (/run/user/0) failed, reason: Permission denied [..., effective(65534, 65534), real(65534, 0)] /source3/smbd/uid.c:448(change_to_user_internal) change_to_user_internal: chdir_current_service() failed! This commit fixes it by setting the `[global]` force user to the user that owns the directories `smbd` needs to access.
