我正在尝试在 FreeIPA 和 Active Directory 之间建立信任。
基础设施详情：
- 3 个 IPA 服务器，彼此之间均有复制（CentOS 7）
- 3 个用于 AD 的域控制器 (Windows Server 2016)
尝试运行以下命令时：
ipa trust-add --type=ad ad.example.net --admin admin --password --server=DC1.ad.example.net
它在日志中产生了以下错误。

现在据我所知，它说我给了它一个无效的域名...但如果我运行：
systeminfo | findstr /B /C:"Domain"
在其中一台注册了域的机器上，它返回：
Domain: ad.example.net
所以我知道我使用的是正确的域名。
有人能解释一下为什么会失败吗？
答案1
基本上，IPA 域名已在 AD 林拓扑中的某个地方使用，而 Active Directory 域控制器拒绝将该域名路由到 IPA。IPA 中的自动拓扑冲突解决程序中的代码没有考虑由于 IPA 名称在 AD 中用作 UPN 而引发此类冲突的情况。
您是否在 AD 中将 example.com 作为 UPN？如果是，则无法使此信任起作用。您需要更改 IPA 域 (=realm)，然后 AD DC 才会接受它。或者从 AD 端删除同名的 UPN。
