Samba 配置，状态[NT_STATUS_ACCESS_DENIED]，

我正在尝试使用 centos7 配置 samba 以便从 windows 10 客户端访问。

日志级别 = 1重新安装 centos 后，我使用了来自同一服务器的以前正常工作的 smb.conf。

日志级别 = 10 您实际上可以跳过阅读此内容，这是第 10 级详细信息。

开始

我对配置 Linux 服务器还很陌生，我熟悉基本的 Linux 命令ls chmod chown ...，

我跟着本文在 wlan 网络上配置安全共享，然后与同事一起测试，一切正常，只是他没有共享的执行权限，路径是/home/CompanyFiles/All

所以我执行了cd /home/

然后chmod -R 777 /

然后我成功更改了整个 centos 文件的权限并破坏了 centos 安装。

经过一番谷歌搜索后，我决定重新安装 centos 比尝试从 chmod 命令中恢复更好，而且由于我只在其上安装了 samba，因此这是可行的，所以我将 smb.conf 复制到另一台机器，重新安装了 centos 并重新安装了 samba，然后我使用了旧的 smb.conf。

结尾

smb.conf：

[global]
        workgroup = WORKGROUP
        security = user
        map to guest = Bad User
        printing = cups
        printcap name = cups
        load printers = yes
        cups options = raw
        log level = 4
        #ntlm auth = yes
        passdb backend = tdbsam
        netbios name = adServer

[homes]
        comment = Home Directories
        valid users = %S, %D%w%S
        browsable = No
        read only = No
        inherit acls = Yes
[CompanyFiles]
        path = /home/CompanyFiles
        guest ok = yes
        browsable = no
        writable = yes

[All]
        comment = Company Access
        path = /home/CompanyFiles/All
        guest ok = no
        browsable = yes
        writable = yes
        #access based share enum = yes

文件夹的权限是：

drwxrwx--x. 3 everyad adusers 17 Feb 26 09:32 CompanyFiles

drwxrwx--x. 2 everyad adusers 42 Feb 26 11:43 All

其中所有用户都是 adusers 组的成员。

尝试访问的用户也是在 smb 上使用以下方式创建的smbpasswd -a username

但是当我尝试从 Windows 10 访问服务器时出现以下错误

您没有权限访问服务器...

请注意，我删除了 Samba 并重新安装，但没有成功。

当制作日志级别 4 时我收到status[NT_STATUS_ACCESS_DENIED]，但使用较低级别时我没有收到错误。

在线搜索总是导致 selinux 内容、防火墙或权限：

selinux 是宽容的

防火墙已禁用

仍然遇到同样的问题

答案1

我终于解决了这个问题。

首先，我使用net use * /delete命令行从 Windows 10 中删除了现有连接，因为凭据已保存，并且我在服务器上更改了它们

另外由于某种原因，我必须smbpasswd在 /etc/samba/smb.conf 中指定：passdb backend = smbpasswd在[global]部分中

/home 权限也是错误的，并且我的所有共享都在 /home 中，因此我将权限重置为 755：chmod -R 755 /home

然后我根据需要重置所有共享权限和组访问。

答案2

我们遇到了 [NT_STATUS_ACCESS_DENIED] 错误，用户可以访问他们的 HOME 共享，但不能访问任何其他共享。

/var/log/samba/__ffff_172.16.0.35.log：

[2019/03/05 11：26：53.914706，1] smbd/service.c:678（make_connection_snum）create_connection_server_info 失败：NT_STATUS_ACCESS_DENIED

这是由于 SAMBA 和 WINBIND 服务器运行时域控制器重新启动而导致的。只需重新启动 winbind 和 smb 服务即可解决该问题。

一个小修复；但值得一提

答案3

我也遇到过这种情况，使用 Fedora 上的最新 Samba。当我尝试从 Windows 创建/写入/删除 Samba 共享子目录中的文件和文件夹时，莫名其妙地收到“访问被拒绝”响应。奇怪的是，更改根文件夹中的文件却没有问题。

我将设置从 更改passdb backend = tdbsam为passdb backend = smbpasswd，然后smbpasswd -a myuser重新添加我的用户和密码，并重新启动 smb 服务。这为我解决了问题。

答案4

Apparmor 也可能是原因。您需要将所有共享位置列入白名单，否则您将始终收到“权限被拒绝”错误。

修复正在添加到/etc/apparmor.d/local/usr.sbin.smbd：

"/path_to_share/" rk,
"/path_to_share/**" lrwk,

对于每个共享。（第一行允许对基目录进行读访问，第二行递归地允许对该基目录中的所有内容进行读写访问）
