ошибка ssh атентификация на сервере по DSA

Есть сервер Gentoo 2008.0, необходимо настроить аутентификацию по ключу. Заходить надо с машины под управлением winxp. Как ssh клиент на winxp использовал putty.

Что делал:

1. С помощью утилиты puttygen произвел генерацию пары ключей, сохранил их, секретный защитил паролем само-собой
2. Открытый ключ скопировал на сервер в ~/.ssh/authorized_keys
3. В /etc/ssh/sshd_config поставил PubkeyAuthrntication yes и перезапустил sshd
4. На winxp запустил pagent добавил секретный ключ, ввел пароль
5. Запустил putty Connection->SSH->Auth->"Private key file for authentification" указал путь к ключу, Connection->Data->"Auto-login username" ввел имя пользователя, в домашней папке которого во втором шаге поместил ключ
   

   При попытке подключения вылетает ошибка "No supported authentification method avaliable".

   Что я сделал не так?

   ДА и вот конфиг сервера:
