In FreeIPA deployment with active Global Catalog service, when a two-way
trust to Active Directory forest is established, Windows systems can
look up FreeIPA users and groups. When using a security tab in Windows
Explorer on AD side, a lookup over a trusted forest might come as
realm\name instead of NetBIOS domain name:

If we are running as a DC and PASSDB supports returning domain info
(pdb_get_domain_info() returns a valid structure), check domain of the
name in lookup_name() against DNS forest name and allow the request to
be done against the primary domain. This corresponds to FreeIPA's use of
Samba as a DC. For normal domain members a realm-based lookup falls back
to a lookup over to its own domain controller with the help of winbindd.
