Issue

  • How to change the hostname of an IPA server?

Resolution

  • The official supported way how to rename the IPA server is the following:

1] Create another replica of an IPA server with desired hostname.
2] Verify that the replicated server is working properly.
3] Configure the newly installed server as CA renewal master and CRL generation master.
4] Disconnect the "old" IPA server.
5] Test all functions against new IPA server with the new hostname.
6] Decommission the old IPA server.

Root Cause

  • There is no supported way how to achieve this task without replication. It is too complex and dangerous to do it on a single machine.
