[Freeipa-users] IPA 4.1.0 UI certificate confusion

[Martin Kosek]

Good. But still, I am curious about your architecture. It almost looks like you 
are installing several FreeIPA servers (ipa-server-install), but with the same 
realm/domain. Can you share the reasoning? Maybe an advise can be given for the 
whole FreeIPA architecture.

It is not something expected, normally you would install one FreeIPA server 
with realm "example.com" and then install replicas (ipa-replica-install) for 
redundancy or load balancing.
