So the user running 'sshd' does not have the proper permissions or support
to change users.  Did you use 'ssh-host-config' to set it up?

This is wrong.  SYSTEM doesn't have the required permissions to switch user
contexts after XP.  You'll need to run 'sshd-host-config' and let it set up 
a new
user (cygserver) to run the service.  If that doesn't work, you may find it
easier to simply wipe your installation and start over.  Alternatively, you can
review 'ssh-host-config' and its supporting scripts to check the permissions and
ownerships of all the necessary files.  'sshd' is very picky about this and 
won't
run properly without all the right ownerships and permissions.
