The ssh-host-config script is supposed to work for simple standalone
environments, not for AD environments.  If you want to use a domain
account, the account must already exist, see

  https://cygwin.com/faq/faq.html#faq.using.sshd-in-domain

The FAQ entry mentions adding the account to /etc/passwd, but that
obviously is not required anymore with 1.7.34 (FAQ needs change).

Also, the current released ssh-host-config script is not 1.7.34-ready.
I sent a few patches upstream already and I was planning to update
the openssh package when I release 1.7.34.

For your convenience, I attached the current upstream ssh-host-config
script.
