PGP Authentication with gpg4win+ssh

Hello All,

I'm trying to get this to work with gpg4win.  I have a Yubikey with a PGP
key stored and it works just fine.  I connect with PuTTY, it connects to
the GPG agent and  it pops up asking for my Yubikey PIN and away I go.

My config looks like this:

Linux side: authorized_keys file has the converted PGP key as RSA keys
added.
Windows side: PGP key is in the Kleopata keyring.  gpg-agent.conf has
enable-putty-support, gpg-connect-agent is running.

I also created an Authentication subkey for my other PGP Key, the only
difference being it's not on my Yubkiey but in my regular keyring with
Kleopatra.  This same key works just fine on my Linux boxes when I use it
for authentication between them but not in Windows.  PuTTY shows no keys
available in the agent and thus my login is rejected.

Is there some setting I'm missing or does gpg4win only support PGP
authentication with SSH via a smart card?

Chris
