ssh 登录 kerberos / winbind 后 SSH 即时注销

  • 772

我设置了一个 ubuntu 服务器，它根据我们的 W2k8 域的活动目录进行身份验证。一切顺利，我在 getent passwd 和 wbinfo 中看到了所有用户。

我希望能够在机器上使用 kerberos 和 winbind auth，到目前为止一切正常。

但是当我使用 AD 用户登录到服务器时，我只看到了 motd 而不是收到提示，而是再次注销。

    好的，通过检查用户详细信息解决了这个问题：非常简单，他们只是没有从 winbind 分配正确的 shell。因此，它只是通过 motd 然后注销。smb.conf : template shell = /bin/bash而已。
