Hi,

As stated in the error, KDC will not work if it resolves to the localhost (::1) address. To fix your installation, modify your /etc/hosts to
```
::1         localhost localhost6
10.27.3.2   freeipa-2.packet.das-schiff.io freeipa-2
```

Take care,

Rafael

I get an error during freeIPA ansible install which does not seem to make sense.

I have the following inventory file:
