29.5. Installing an IdM replica configured to use eDNS

You can install an IdM replica with eDNS in an environment where the IdM server has DoT enabled.

When you install the replica with the integrated DNS service, the replica uses the same configuration as the IdM server. It runs BIND to handle incoming DNS queries, including encrypted queries, and uses unbound for outgoing encrypted DNS traffic.

When you install the replica without the integrated DNS service, the replica inherits the client-side configuration. It uses unbound with a DoT forwarder to send encrypted DNS queries to the IdM DNS server.
