We have added some readme files to the packages that explain why and
how it is done. Andreas takes great deal to test that packages
actually build both with AD DC disabled and enabled in Fedora. So, one
could rebuild the package and get fully working Samba 4.0 AD DC with
embedded Heimdal version. However, that package will be incompatible
with certain other packages that use Samba libraries et al due to
Kerberos API drift. I'm thinking on adding some guards through the
generated names and versioning so that once you rebuild samba package
with AD DC functionality, it will supersede stock samba package in
Fedora so that no updates will break the install. You'd need to
rebuild src.rpm then to get updates for yourself. So much we can do
before we'll get MIT Kerberos working as embedded KDC for Samba 4.0.

There is one change in registry.tdb that breaks downgrades since
registry format changed between 3.6 and 4.0 smbd. This applies to both
AD DC case and (F18-default) build without AD DC
