I just checked and it works for me. Here is what I did:
- generate a private/public key on windows using puttygen.exe
- paste the public key in ~/.ssh/authorized_keys2 on linux followed by
username@windowsaddress
- launch pageant.exe on windows and load the private key
- test that it works with putty with connection auto-login username
set: you should get in linux without entering any password or phrase
