Ticket was cloned from Red Hat Bugzilla (product Red Hat Enterprise Linux 7): Bug 1619738

Description of problem:

customer would like to have a list of replicas to which client will failover.

Today, we use default.conf + DNS.

We have also provided solution regarding "locations" but this is not acceptable
for the customer.

Version-Release number of selected component (if applicable): RHEL-7.5

More details:
Not all IPA hosts have access to all IPA servers, because they are located in a variety of different security zones in their environment (some may not even have routing rules to all IPA servers in the enterprise).

This is quite a valid (though edge) use case for environments with an isolation or high cost links between zones and no use of IPA locations functionality (external DNS, etc). We need to investigate better ways here. It may require creating a guidance document and/or extending existing code. For this reason we clone it to FreeIPA pagure.
