[Freeipa-users] Switching a client from one set of IPA servers to another

[Bret Wortman]

I'd like to test migrating our clients from the old IPA infrastructure to our newer F20-based servers but am having trouble with our first clients. Unenrolling them from the old IPA servers went fine, but when I try to enroll them with the newer ones, the logs report:

Failed to verify that zsipa.foo.net is an IPA Server.

:
Installation failed. Rolling back changes.
IPA client is not configured on this system.
# ps aux | grep firewalld| grep -v grep
# getenforce

# cat /var/log/ipaclient-install.log

I removed the timestamps for readability.

INFO Please make sure the following ports are opened in the firewall settings: Also note that following ports are necessary for ipa-client working properly after enrollment: It seems to me that something from the old version is hanging around and getting in the way, or that something in the setup of the new server isn't quite complete -- which seems more likely, and where should I be looking for the actual cause? Is this a problem with a certificate or with the server not being discoverable?
