Problems with OpenSSH_2.2.0p1 & Cygwin 1.1.4 on NT

[Gil Markham <gmarkham at aventail dot com>]

Okay, I've seen other people mention the problem I'm having with sshd in the
mailing list archive but haven't found anyone answering with a solution.  I
have verified that my permissions are correct ("Increase Quotas","Act as
part of operating system", etc..) for doing NT password based
authentification.  I have verified that my client works correctly be
connecting to a Solaris 2.6 machine running sshd.  I have verified that my
/etc/passwd and /etc/sshd_config are correct and have the correct newlines
at the end of each line (set fileformat to unix in vim and wrote out the
file).  

I have a clean install of Cygwin 1.1.4 with OpenSSH_2.2.0p1 which was the
latest as of yesterday (Oct. 2nd).

I'm not sure what I should have for my CYGWIN environment variable (is there
a reference for this?) but its currently set to:
tty ntsec binmode glob title strip_title

I'm using a home directory for the user of: //c/home/gmarkham 
The users shell is: /bin/sh 

The output from 'sshd -d' is as follows when trying to connect via ssh1 on
the local machine:

And my sshd_config look like:

#Uncomment if you want to enable sftp

Any help on figuring out why this fails after starting the interactive shell
would be much appreciated.
