Prior to my employment, one of our engineers setup an IPA server to replace the horrific OpenLDAP server.  One of my first tasks was to build a second IPA server and setup replication.  Initially, the replication setup was smooth and simple.  (I used this: https://www.howtoforge.com/installing-freeipa-with-replication for getting replica up.)

However, as we were starting to consider how best to deploy it to our remote servers, and digging through the GUI I got this pop-up when looking at the Topology page:

It is strongly recommended to keep the CA services installed on more than one server.

As this replica needs to be a full 'replica' of the primary, I went about trying to install the CA role on the second server, which I'll call IPA1 and the master IPA0.  The RH documentation says to 'Run ipa-replica-install with the --setup-ca option.'  Of course, the documentation doesn't explicitly say whether that needs to be done on the initial creation of the replica, or if it can be done after the replica was created.  (IOW, it just adds the CA services role and pulls from IPA0 the CA stuff it needs.)

Unfortunately, that failed and I ended up uninstalling the replica with 'ipa-server-install --uninstall' after removing the replica from IPA0.  After a reboot (just in case), I built a new replica GPG file on IPA0, copied it over to IPA1 and ran this:

ipa-replica-install replica-info-ipa1.neonova.net.gpg --setup-ca

That also failed with the exact same error as the failure from trying to install just the CA role on the existing replica. This is the error I get:

 [2/27]: configuring certificate server instance

ipa.ipapython.install.cli.install_tool(Replica): ERROR    The ipa-replica-install command failed. See /var/log/ipareplica-install.log for more information

Also, in the pki-tomcat/ca/debug log I get this:

Failed to contact master using admin portjavax.ws.rs.InternalServerErrorException: HTTP 500 Internal Server Error

javax.ws.rs.NotFoundException: HTTP 404 Not Found

We have a signed Wildcard Cert from GoDaddy on IPA0, but I can't tell why this even needs to contact the Cert CA for any reason. 

BTW, I had this wildcard cert setup for the IPA web interface only prior to blowing this thing to pieces over partial documentation and God knows what else isn't spelled out that I missed.

Any ideas?
