尝试设置 FreeIPA 时出现以下错误：

==============================================================================
This program will set up the FreeIPA Server.
This includes:
* Configure a stand-alone CA (dogtag) for certificate management
* Configure the Network Time Daemon (ntpd)
* Create and configure an instance of Directory Server
* Create and configure a Kerberos Key Distribution Center (KDC)
* Configure Apache (httpd)
* Configure DNS (bind)

Checking forwarders, please wait ...
ipa : ERROR Forwarder 62.141.32.3 does not work

FreeIPA server configuration failed.
我检查后发现，该 IP 地址只是我的 的第一个条目/etc/resolv.conf。它确实是管理界面为我的根服务器提供的指定名称服务器之一的正确 IP 地址。
这种设置的起源是这Docker 容器。
