Why not? It's a recommended best practice to choose a subdomain of your
primary domain (e.g. "ad.example.com"), and then add alternate UPN
suffix which allows user logons to match their email addresses.
In fact, this page on the Samba Wiki recommends just that:

My mistake: I actually installed both libpam-winbind and libnss-winbind.

Fair enough. I attempted this out of convenience since I was familiar
with Realmd. My biggest concern was the ability to control which
groups can login, but it looks like I can still do this with winbind by
instead using /etc/security/access.conf:
I wrote a second blog post which goes on to configure libnss-winbind:

This was somehat intentional. My machines are given a different DNS
server via DHCP (both on pfSense). I've delegated the AD zone to the
Samba DC. So, the AD DNS server should only receive requests for
which he is authoritative. Is this a valid assumption?
