That's not true, and I'm not even sure it's possible from samba (at least, I'm
not sure it *should* be possible).

I have a machine with an A record that matches the keytab entry ("real").  The PTR
record for the IP goes back that the hostname.  There's then a CNAME record
for the name used in reality for the web server ("friendly").

A client will access:

https://www.friendly/kerberised

Client correctly pulls down HTTP/real@KRB-REALM, and the authentication works
just fine.
