Authentication Ssh dsa密钥身份验证失败

我正在尝试使用以下生成的dsa密钥文件登录到cygwin中安装的openssh服务器：

ssh-keygen -t dsa

我已使用以下方法将我的密钥复制到授权密钥：

ssh-copy-id -i ~/.ssh/id_dsa ltonon@localhost

我还在/etc/sshd_config中配置了ssh服务器（默认情况下，其他所有内容都被注释掉）：

在/etc/ssh_config中（默认情况下，其他所有内容都被注释掉）：

现在，当我尝试使用以下工具登录时：

ssh -vvvv -i .ssh/id_dsa ltonon@localhost

我有以下资料：
