我安装了一个新的 Openmediavault 4 服务器，并将其加入了由两个 Samba 4 域控制器管理的 Active Directory。
规格：
- Active Directory 域我的广告域由两个 Samba 4 域控制器管理（服务器-z1.my.ad.域 (192.168.70.201)和服务器-z2.my.ad.域 (192.168.70.202)
- 一台文件服务器Samba 版本 4.5.12-Debian正在运行Openmediavault 4.1.0-1（基于 Debian 9）
- 文件服务器的 IP 地址是192.168.70.171
- 文件服务器的 FQDN 是 server-f1.my.ad.domain
- 文件服务器有别名服务器-f10.my.ad.域在 DNS 中配置
- 我想使用 IP 地址从客户端访问文件服务器（\192.168.70.171)、FQDN（\服务器-f1.my.ad.域) 和 DNS 别名 (\服务器-f10.my.ad.域）。
我按照以下指南使用 SSSD 加入 Openmediavaulthttps://forum.openmediavault.org/index.php/Thread/18886-Guide-how-to-join-OpenMediaVault-3-x-in-an-Active-Directory-domain/getent passwd，即使重启后我也可以列出域用户。
我遇到的问题是，我可以使用 FQDN 连接到 Openmediavault 来访问 Samba 共享（\服务器-f1或者\服务器-f1.my.ad.域），但不使用 IP 地址（\192.168.70.171）或 DNS 别名（\服务器-f10或者\服务器-f10.my.ad.域）。
当我使用 IP 地址或 DNS 别名访问时，Openmediavault 系统上出现以下错误：

请问你能帮帮我吗？
谢谢！
答案1
虽然这是一篇较旧的帖子，但我今天刚刚遇到这个问题，所以我分享了我的解决方案。
将计算机加入 Active Directory 时，将为生成的计算机帐户创建两组 SPN，一组在 FQDN 上，第二组在 Netbios 名称（又名服务器名称）上
Netbios 名称限制为 15 个字符。因此，在我的情况下，服务器名称长度超过 15 个字符 - 因此当我将其加入域时，计算机帐户的生成的 SPN 从第 15 个字符开始被截断。但是带有 FQDN 的 SPN 是完整的 - 因此使用服务器名称访问共享会失败，而使用 FQDN 访问则可以。
修复活动目录中的 SPN 对我来说很有效，对你来说应该也会有用（但不适用于 IP 地址 - 因为你需要 NTLM）
将 SPN 添加到计算机帐户后，您可能还需要重新启动服务器。
答案2
您不能使用 IP，因为 Kerberos 仅绑定到 FQDN。
