SSH权限被拒绝（公共密钥），但root ssh可以工作

我正在尝试为在DigitalOcean Ubuntu 12.04服务器上用Chef创建的用户帐户设置ssh访问权限。我在DigitalOcean中设置了选项，以便在创建Droplet时自动复制Mac的ssh密钥。

我可以毫无问题地以root用户身份登录，但其他用户无法通过身份验证。这似乎是一个常见问题，我检查了其他一些答案，并找到此命令以获取更多信息：

ssh -vvv -i id_rsa user@serverIP

使用该命令的root用户（成功）的日志为

调试

1: Offering RSA public key: /Users/evan/.ssh/id_rsa
debug3: send_pubkey_test
debug2: we sent a publickey packet, wait for reply
debug1: Server accepts key: pkalg ssh-rsa blen 279
debug2: input_userauth_pk_ok: fp snip!
debug3: sign_and_send_pubkey: snip!
debug1: read PEM private key done: type RSA
debug1: Authentication succeeded (publickey).

失败的用户：

调试

1: Authentications that can continue: publickey
debug3: start over, passed a different list publickey
debug3: preferred publickey,keyboard-interactive,password
debug3: authmethod_lookup publickey
debug3: remaining preferred: keyboard-interactive,password
debug3: authmethod_is_enabled publickey
debug1: Next authentication method: publickey
debug1: Offering RSA public key: /Users/evan/.ssh/id_rsa
debug3: send_pubkey_test
debug2: we sent a publickey packet, wait for reply
debug1: Authentications that can continue: publickey
debug1: Trying private key: /Users/evan/.ssh/id_dsa
debug3: no such identity: /Users/evan/.ssh/id_dsa: No such file or directory
debug2: we did not send a packet, disable method
debug1: No more authentication methods to try.

在我看来，这意味着公钥不正确。但是，如果我以root用户身份登录并转到

home/otheraccount/.ssh/authorized_keys

然后我可以看到我的ssh密钥在那里。我以为可能有错误，所以我做到了：

cp .ssh/authorized_keys ~/home/otheraccout/.ssh/authorized_keys

但这没有帮助。我不知道还能去哪里。

如评论中所建议，/var/log/authlog包含：

Apr 21 04:59:30 localhost sshd[586]: User deploy not allowed because account is locked
Apr 21 04:59:30 localhost sshd[586]: input_userauth_request: invalid user deploy [preauth]

我试着做：

sudo usermod --expiredate -1 deploy

它返回：
