That's not what I'm talking about. The /bin/sh entry in /etc/passwd
isn't the home directory field but the login shell field. As it's
visible in the below /etc/passwd, you didn't enter your home directory
in the appropriate field. You know the layout of the /etc/passwd field
in U*X systems? If not, assuming your home directory is /home/johnl,
you'll have to change the line

 johnl::500:513:,S-1-5-21-...-500::/bin/sh

to

 johnl::500:513:,S-1-5-21-...-500:/home/johnl:/bin/sh

ssh and sshd always use the home directory entry in /etc/passwd,
never $HOME.

No, this are SIDs, a Windows NT datastructure. I suggest reading the
documentation under

http://sources.redhat.com/cygwin/docs.html

especially the chapter about NT security:

http://sources.redhat.com/cygwin/cygwin-ug-net/ntsec.html

> During the ssh-config, I was prompted twices to enter a phrase, I entered the password for johnl, as the phrase.

Which isn't needed. Again, read the documentation, in case of ssh
I suggest reading the man pages for ssh and friends which are
installed on your system after the standard install.
