Samba 共享 - 如何限制对 Active Directory 组的访问

Question

我正在 Active Directory 域环境中工作，并尝试配置一些 Samba 共享，以便 Windows 客户端可以访问 SUSE UNIX 服务器上的某些目录。

对每个共享的访问需要仅限于特定的 AD 组。

我的 smb.conf 文件如下所示，但当导航到 Windows 共享表单时，我收到凭据提示或访问被拒绝消息。当我使用 \\SERVER_NAME 或 \\IP_ADDRESS 浏览到服务器时，我还在 Samba 日志中看到略有不同的消息。

[global]
    netbios name = SERVER-NAME
    security = domain
    realm = MYDOMAIN.ORG.UK
    workgroup = MYDOMAIN
    password server = *
    idmap config * : range = 10000-20000

    cups options = raw
    kerberos method = secrets and keytab
    logon path = \\%L\profiles\.msprofile
    logon home = \\%L\%U\.9xprofile
    logon drive = P:
    map to guest = Bad User
    passdb backend = tdbsam
    null passwords = yes
    printing = cups
    printcap name = cups
    printcap cache time = 750
    template homedir = /home/%D/%U
    template shell = /bin/bash
    usershare allow guests = no

    winbind refresh tickets = yes
    winbind offline logon = yes
    winbind cache time = 10
    winbind enum users = yes
    winbind enum groups = yes
    winbind use default domain = yes

    log file = /var/log/samba/samba.log
    max log size = 1000
    log level = 2

[share1]
        path = /path/to/share/1
        read only = yes
        browseable = yes
        valid users = @ad-group-for-share-1

[share2]
        path = /path/to/share/2
        read only = no
        browseable = yes
        valid users = @ad-group-for-share-2

浏览到 \\servername\share1... 时，samba 日志显示以下内容

[2019/05/30 11:21:01.182411,  1] ../source3/auth/token_util.c:431(add_local_groups)

浏览到 \\ip-address\share1 时，Samba 日志显示以下内容

[2019/05/30 11:22:01.416559,  2] ../source3/auth/auth.c:305(auth_check_ntlm_password)

我缺少什么？我该如何解决这个问题？需要做什么才能让 Windows 客户端访问这些共享？
