No, this is exactly the way to do it.  ssh-host-config cannot create a
privileged domain account when run as any user from any machine so it
doesn't try to.  If you need a domain user to be able to authenticate with
pubkey, you have to do what you did to make that work.  The side effect
of locking the domain guest account is a new twist I hadn't heard of
before but then again, it is Windows we're talking about. ;-)
