[Freeipa-users] Ansible FreeIPA Server + Replica

Hi, I'm new to FreeIPA and the ansible-freeipa collection. I can successfully install IPA server using the role ipaserver. However, I want to setup a multi-master replication with failover. As far as I know I need to install ipaserver on all of my masters/replication and then the replica role? How does the master nodes establish a relationship? Is this done using IPA client? It might seem weird, but my goal is to setup the IPA server purely as a LDAP server using external CA. This is because we want to have the ability to have a user interface like the web gui.
