Samba Share 对每个人都可写

Question

我无法使我的 samba 共享正常工作。我的目的是托管一个可供所有人（包括来宾）写入的目录。为此，我创建了一个拥有相应目录的用户和组：

drwxrwsr-x 19 transferuser transfergroup  4096  Dez 14 12:43 Transfer

在我的 smb.conf 中，我尝试了在多个线程中找到的数十种配置组合。我可以浏览目录并读取所有文件，但没有写权限。我使用 Dolphin 从运行 Kubuntu 19.10 的机器浏览目录。该服务器也运行 Kubuntu 19.10。最初我是这样认为的，fource user并force group会自动为该用户应用 unix 权限。但是由于该用户拥有该目录，因此他拥有完全访问权限。我如何允许每个用户（和来宾）拥有写权限？这是我目前的 smb.conf：

[global]
  security = user
  map to guest = bad user
  unix extensions = no

[...]

[Transfer]
path=/media/shared/6TB2/Transfer/
read only = no
comment=
force user = transferuser
force group = transfergroup
writable = yes
browsable = yes
public = yes
create mask = 775
force create mode = 775
security mask = 775
force security mode = 775
directory mask = 2775
force directory mode = 2775
directory security mask = 2775
force directory security mode = 2775
inherit permissions = yes

编辑 1：通过编辑 smb.conf 创建共享。输出net usershare info --long为空的. 的输出testparm -s为：

Load smb config files from /etc/samba/smb.conf
