Thanks for the spot-on advice. Jeff Bales' procedure was a great start,
needed a few tweaks. The server fully functioning as a DC, I was able to
get homes working by adding this bit of magic to [homes]:
root preexec = bash -c '[[ -d /home/%U ]] || mkdir -p -m 0700
/home/%U && chown %U:users /home/%U'
I have this configured in a VMWare environment, so there is no reason
not to setup a separate DC, but that will have to keep for another day.
