That would be just setting up FreeIPA and maintaining correct DNS records, so I won't jump into this one. > Integrate my existing internal DNS server with FreeIPA's DNS, so I can manage internal DNS records within FreeIPA while maintaining the internal DNS functionality. > Is a short answer: you can't. The longer answer might provide a way to almost have what you want. FreeIPA's embedded nameserver has to be authoritative, and you can only manage its records, not the ones on your current DNS infrastructure. To change DNS management to FreeIPA you'd have to set your internal DNS nameserver to be a secondary nameserver, and configure FreeIPA's nameserver to notify the internal nameserver of changes. It's doable, but I would not recommend doing so. Another possibility is to change DNS infrastructure to use FreeIPA instead of the current nameserver. If you can manage your internal zones with the limitations that FreeIPA's nameserver has (e.g. split-view is not supported), then you could plan on retiring the current nameserver in favor of the FreeIPA one. With replicas you can also get redundancy on the nameservers. If your current nameserver is exposed to the world, again, I'd suggest against this move. Bottom line, either use your current DNS infrastructure or fully migrate to FreeIPA. Rafael > I want to avoid any conflicts between FreeIPA's DNS and my existing internal DNS server.
