CentOS 6.3 FreeIPA Server (Fully Configured), stock -> CentOS 6.4

CentOS FreeIPA Server
----------------------
The server appeared to function correctly after a reboot, I ran several
IPA commands to ensure user database was intact and also to ensure
hosts DB was intact.

Again server appeared to be running fine, I checked logs and only found
errors moaning about PPM being too high for NTPD.

Further investigation into logs indicated NTP was able to sync time
successfully anyway.

This could be due to the Hypervisor's clock.

But aside from that, it appeared to function correctly :-).

So marking as "Successful".

I haven't had time to test from CR as of yet (tbh may not have time before GA even) but as a heads up from the upstream mailing list there does exist a condition where the IPA web interface will fail on an upgrade due to a schema issue:

https://www.redhat.com/archives/freeipa-users/2013-February/msg00391.html

The errata is coming to fix it and it only affects IPA installs that started in 6.2 and were upgraded to 6.3 (so started life at IPA 2.0 topologies) it seems... IPA systems installed in 6.3 initially are reported to be fine and there is a manual workaround.

However upstream is recommending people not update their systems until the errata is out (and I guess include that during the update rather than to the 6.4 'point in time') ...

Depending on when the CentOS 6.4 GA is this might be a required note in the release notes...
