[Freeipa-users] ipa-client-install fails on replica because of kinit cannot contact any KDC

[Shree]

Rob
You were right. After upgrading the client to the ipa-client-3.0.0-37.el6.x86_64 version I started seeing a warning during the client install that went something like 
=================
Autodiscovery of servers for failover cannot work with this configuration.
If you proceed with the installation, services will be configured to always access the discovered server for all operations and will not fail over to other servers in case of failure.
Proceed with fixed values and no DNS discovery? [no]: yes
=================

I continued by saying yes because in my case the master and the replica are in different VLANs and failover is not possible for me. I have tried in two hosts successfully and am hoping that does the trick.

However I see one issue immediately that my sudo access does not seem to work now on the newly added clients! Do you know what might be happening?

You'll definitely want to update to 2.2.0-17, that fixes CVE-2012-5484

Unfortunately our logging around discovery was rather horrible in 2.2.x 
so it is difficult to know exactly what is going on.

I believe the problem is that it is still doing DNS discovery even 
though you've passed in a server name so it is setting up Kerberos to 
look up the KDC which it finds but can't talk to.

This should be fixed in the 3.0 packages so updating to those is the 
preferred solution.

For 2.x you can try the --force option which should make it skip some 
discovery.
