Cygwin sshd public key authentication failure

Wondering if anyone can help me with this problem. I am trying to setup
Cygwin DLL 1.3.18-1 release and OpenSSH 3.5p1 on a system running Windows
NT4 SP4 to accept public key authentication from a Redhat 7.1 box using
OpenSSH 3.4p1. I am able to setup the auth from the NT box to the Redhat
system just fine, but keep failing the other way.

I have tried both RSA and DSA key authentication with no success. I have
checked and double checked the permissions on the .ssh directory and the
authorized_keys file below (Note - I have replaced the account name with
"noname"), as well as tried them with 755 and 644 permissions:

drwx------+ 2 noname SYSTEM 4096 Jan 15 11:35 .ssh
-rw------- 1 noname SYSTEM 1451 Jan 15 11:39 authorized_keys2

Below you will find the debugging output from the attempted key exchange:

I have looked through every possible link on the net and the newsgroups but
find no answer to my problem. I did find a reference on a webpage that
stated there was some issue with using public key authentication from a
RedHat box to an NT box, but no answer as to why or how to solve it.

Thanks in advance,

Greg
