Samba 写访问问题：即使在 smb.conf 中，参数也不显示在 testparm 中

我正在尝试获取 samba 共享设置，以便用户同时拥有读取和写入权限。我认为我可以通过编辑 /etc/samba/smb.conf 来添加我的共享，如下所示：

[CLOUD]
   path = /cloud
   writable = yes
   security = user
   valid users = neon, win
   write list = neon, win

然后运行：

$ sudo systemctl restart smb.service
$ sudo systemctl restart nmb.service

我可以从这两个帐户访问我的共享，但都不能写。当我运行 testparam 时，一些参数丢失（security和writable），但没有明确的错误。

    dns proxy = No
    log file = /usr/local/samba/var/log.%m
    max log size = 50
    server role = standalone server
    server string = Samba Server
    workgroup = MYGROUP
    idmap config * : backend = tdb


[homes]
    browseable = No
    comment = Home Directories
    read only = No


[printers]
    browseable = No
    comment = All Printers
    path = /usr/spool/samba
    printable = Yes


[CLOUD]
    path = /cloud
    read only = No
    valid users = neon win
    write list = neon win

我认为这意味着该writable = yes参数未被识别，但由于没有错误，我不知道为什么。关于这里可能发生的事情有什么建议吗？我正在使用拱门。
