无法在 Samba 服务器（CentOS）上查看或创建文件

Question

我正在尝试使用 CentOS 7 和 Samba 设置文件服务器。我可以连接到服务器，并且可以打开我在服务器上设置的共享文件夹。但是，我看不到内容，也无法创建新文件或文件夹。尝试查看内容只会导致 Windows 10 显示该文件夹为空（但实际上不是），并且尝试在其中一个共享文件夹中创建新文件或文件夹会导致拒绝访问消息，即使我输入了拥有该文件夹的帐户的凭据也是如此。

我尝试在 smb.conf 中将该帐户作为有效用户，但没有成功。在 smb.conf 中将 guest ok 切换为 on 也没有用。

我的配置文件如下：

# See smb.conf.example for a more detailed config file or
# read the smb.conf manpage.
# Run 'testparm' to verify the config is correct after
# you modified it.

[global]
        workgroup = SAMBA
        security = user

        passdb backend = tdbsam

        printing = cups
        printcap name = cups
        load printers = yes
        cups options = raw

[homes]
        comment = Home Directories
        valid users = %S, %D%w%S
        browseable = No
        read only = No
        inherit acls = Yes

[printers]
        comment = All Printers
        path = /var/tmp
        printable = Yes
        create mask = 0600
        browseable = No

[print$]
        comment = Printer Drivers
        path = /var/lib/samba/drivers
        write list = @printadmin root
        force group = @printadmin
        create mask = 0664
        directory mask = 0775

[programming]
        path = /srv/samba/programming
        read only = no
        guest ok = yes

[video]
        path = /srv/samba/video
        read only = no
        guest ok = yes

我究竟做错了什么？
