No it is not necessary to have 2 different domains, unlike Active
Directory, FreeIPA can manage clients in multiple DNS domains within a
single REALM. It requires a bit of caution in setting up FreeIPA, and in
some cases some configuration in older clients to associate the REALM to
the DNS name, but it is possible to have a single domain serve multiple
DNS domains.
Also it is not true you can have only one Domain Controlle rper Domain,
you can have multiple DCs per Domain that replicate data between them.
FreeIPA in particular supports only multi-master configurations.

Simo.
