Rene,

Really appreciate you taking a look at this.

After trying everything possible as described in my first e-mail I 
reset/uninstalled everything including cygwin, registry entries, path 
variables, cygwin variables etc. Then I reinstalled cygwin and openssh, 
ran ssh-host-config and emailed this list server. So you are right, I 
currently had not run ssh-user-config on this install. I also no longer 
have a sshdproc user with the rights I originally stated because I 
wanted to start from scratch. I wasn't sure how much I had done before 
was right or wrong. So, I now ran ssh-user-config and generated key 
files. they ended up in /home/dan/.ssh as you suggested. I cat'd them to 
authorized keys and still there is a login problem. It appears the key 
file format may be wrong. here is the output now of ssh -vvv localhost.

Should I recreate the sshdproc user with appropriate rights before we 
continue?
