Gods. Sorry about that, I've occasionally pitched in on Samba ports
since.... 1993, with SunOS 4.1.2, I think? I should know your name
better than that.

Yeah. I got that part.

Then I really wish they'd stop publishing empty packages labeled
"samba-dc".  It's confusing and irksome.

The whole point of the backports for RHEL is to enable the full domain
controller feature list. I've followed your advice, and it is
compiling well with Heimdal enabled for both Fedora and for RHEL 7.
Doing it the way you said, and allowing the Heimdal Kerberos to be
used for the dc is working well in my limited testing.

I agree with the philosophy, and had not appreciated the risk that I
was importing from the current Fedora upstream practices.

It does.
