Trouble with RSA authentication

[Marcos Lorenzo <marcos@it.uc3m.es>]

I finally got sshd working!

But I cannot authenticate via RSA. I made the keygen with ssh-keygen in my
winbox and copied identity.pub to authorized_keys and identity in my
linbox (I have the same files in both machines). I really know how ssh
works in linux, but I have some troubles with RSA in cygwin. Below is the
message that I got:

marcos@mozart.lab's password:

My sshd_config is:

marcos@MOZART ~$ grep -v ^# /etc/sshd_config | grep .
Port 22
Protocol 2,1
LoginGraceTime 600
PermitRootLogin yes
StrictModes yes
RSAAuthentication yes
AuthorizedKeysFile     %h/.ssh/authorized_keys
PermitEmptyPasswords no
X11Forwarding yes
UsePrivilegeSeparation yes
Subsystem      sftp    /usr/sbin/sftp-server

I set RSAAuthentication and AuthorizedKeysFile just in case it was
defaulting to no... but this doesn't work neither.

thx in advance,
m4c.
