If you want/have to use domain user logins, then you need to create a
domain equivalent of 'cyg_server'.  You can use the scripts that
'ssh-host-config' uses as a guide to do this but the actual process
must be done by hand and you need access and permission on your domain
controller to set this up.

'ssh-host-config' will not handle this case for you.

For local users, no, no problem.

'ssh-host-config' will set these up for you.  I suggest you use it.

Yes, this information is obsolete.  This is the main reason we
recommend not using various How-To guides that you'll find littered
around the Internet.

> Any other hint?

If a domain service account isn't an option, look at the other
options listed in the User's Guide:

Method 2 or 3 might be sufficient for your need.
