I really appreciate your help, please bear with me. At this point I need to take you back to my ipa-replica-install and what happened there.
[1] My command: ipa-replica-install --setup-ca /var/tmp/replica-info-ldap2.mydomain.com.gpg --skip-conncheck
This ended with a
Done configuring NTP daemon (ntpd).
A CA is already configured on this system.
[2] So did a pkiremove with the following command
# pkiremove -pki_instance_root=/var/lib -pki_instance_name=pki-ca -force
[3] Re ran the ipa-replica-install command in step 1
The install went a little further but ended below.
Configuring directory server for the CA (pkids): Estimated time 30 seconds
[1/3]: creating directory server user
[2/3]: creating directory server instance
[3/3]: restarting directory server
Done configuring directory server for the CA (pkids).

Your system may be partly configured.
Run /usr/sbin/ipa-server-install --uninstall to clean up.
Configuration of CA failed
If I skip the "--setup-ca" option then the replica gets created without any CA services. The "master" and "replica" are in sync but I am unable to run a ipa-client-install using the replica. Now I need to fix this to get a replica in place correctly.

It is part of IPA but the IPA server talks to it, not the clients directly.
I can only speculate what the client is doing without seeing the log
files, but I suspect both masters are in DNS and IPA is trying to enroll
to the initial master which isn't available.
