Well thanks to this:
http://www.freeipa.org/page/Howto/Change_Directory_Manager_Password

I have gotten a little further down the road an created a new
cacert.p12 which looks to be complete.

However, installation still fails in the same place:

So some of the required certificates must be missing still.

Unhelpfully, the ipa-server-install --uninstall process is not
cleaning up everything after this failure, it leaves the CA intact and
the next run through the installer believes the CA is working so it
does not configure it. As such, I guess a re-install is necessary or
some other steps to truly clean everything that I haven't found yet.
