RHEL 7.2：使用领域加入 AD 域

Question

我全新安装了 RHEL 7.2 服务器，我想将其加入 AD 域。我已经在 AD 中预先设置了计算机名称，当我按照Red Hat Enterprise Linux 7 Windows 集成指南中的说明进行操作时，会发生以下情况。

我在我的部门使用拆分DNS：权威的校园范围的DNS服务器运行BIND并且不支持动态更新，所以我在我的部门运行了一对Windows DNS服务器。

想法？

谢谢！

我在尝试加入 CentOS 7.2 服务器上的 AD 域时遇到了相同的错误消息。然而，与指示相反，仅传递用户名对我有用：

realm join example.edu -v -U 'adm-jsmith'
