Don't complain to us about that.  Complain to the site's owner.  This list
doesn't support 3rd-party anything.  If you're having trouble after using
anything not associated with the cygwin.com site, your best bet is to
proceed right back to the source of the information you used and query
them.

Cygwin supported installation information is found in /usr/share/doc/Cygwin.
There's a README there for openssh.  You should read and follow that to
configure openssh.  If you have problems, first start by uninstalling
openssh and get rid of any files you touched in the process.  Then try
installing again, following the configuration info provided in the README.

Import?  No.  'mkpasswd' creates and '/etc/passwd' with your Windows SID
info so that your Cygwin UID can be related back to the SID.  No passwords
are "imported".

Yes.  Don't start Cygwin from the command line as you.  If you
*must* run it from the command line and you're running on XP or less,
Google the cygwin site for "SYSTEM-owned shell".  This will tell you how
to open a shell running as SYSTEM so you can safely start 'ssh' the
same way as it is started as a service.
