Certificate placement in OpenSSH for Windows

I'm trying to use scp to copy files from a SCO box to a Windows 2003
box running OpenSSH.

I generated a key on the SCO box and transferred the id_rsa.pub file
over to the OpenSSH box.  I created a directory ".ssh" on what I think
is the home directory of the userid I'm sending to.

I know that OpenSSH on Windows works, because when I am prompted for a
password on the SCO box, and enter it correctly, the file gets
transferred.  Since I don't specify an absolute path on the target
Windows box, I'm guessing that where the file ends up is the home
directory, and the information in Windows OpenSSH's etc\passwd file
seems to back that up.

If I were to troubleshoot this on a LUnix box, I'd interactively start
sshd in debug mode on the target machine, and look at the output after
a transfer or login attempt.

As it is, I don't even see any log information in OpenSSH's
var\log\OpenSSHD.log.  The file is empty.

So, is there a debug mode in OpenSSH for Windows?  Is there a way to
get logging turned on?
