IPA and Puppet

Hi,
I was wondering if anyone else has managed to integrate Puppet (configuration management) and IPA.

I sort of did this by importing information from an IPA realm (hosts and host group membership) in to the correct puppet files on the puppet master.

The net result is that when a host is added/changed to a certain IPA host group, and there is a puppet class matching the host group name of IPA than that host gets that puppet class applied.

Think of it being a little like MS AD group policy.

Has anyone else played with something like this?
