验证域用户进行 ssh 连接时出错

验证域用户进行 ssh 连接时出错

我正在尝试使用以下方法将我的 Windows 10 机器设置为 ssh 服务器Win32的OpenSSH。该服务器是域的一部分，因此我使用命令

ssh -i ~/.ssh/id_rsa  -l user@domain ip_address

从我的 ssh 客户端连接。

这会出现错误“权限被拒绝（公钥，键盘交互）”。在服务器端，日志显示

sshd：来自 ip_address 端口 59676 的无效用户 user@domain

sshd：无效用户 user@domain ip_address 端口 59676 [preauth] 关闭连接

我还尝试了 ssh 命令的以下变体

ssh -i ~/.ssh/id_rsa  domain/user@ip_address

尝试从客户端进行连接。我收到“通过 ip_address 端口 22 重置连接”错误。

如果我查看服务器端的日志，它会显示：

sshd：错误：lookup_principal_name：用户‘domain\user’的用户主体名称查找失败（显式：5，隐式：5）”

sshd：错误：get_user_token - 无法在第二次尝试中为用户 domain\user 生成令牌

sshd：致命：ga_init，无法解析用户域\用户

我该如何解决这个错误？

细节

在服务器（Windows 10）端：

whoami确认我的用户名是 domain\user

我只想使用公钥身份验证，因此我将 sshd_config 中的权限设置为

PubkeyAuthentication yes
PasswordAuthentication no

所有其他设置均为默认设置。完整的 sshd_config 文件如下

# This is the sshd server system-wide configuration file.  See
# sshd_config(5) for more information.

# The strategy used for options in the default sshd_config shipped with
# OpenSSH is to specify options with their default value where
# possible, but leave them commented.  Uncommented options override the
# default value.

我已将 id_rsa.pub 附加到 C:\Users\user\.ssh 目录中的 authorized_keys 文件中。icacls .\authorized_keys返回

C:\Users\user\\.ssh\authorized_keys NT AUTHORITY\SYSTEM:(I)(F)
                  BUILTIN\Administrators:(I)(F)
                  DOMAIN\user:(I)(F)

在客户端（Ubuntu 20.04.3）端：

~/.ssh/id_rsa 具有以下权限

-rw------- 1 ubuntu ubuntu 2655 Dec 30 18:16 id_rsa
-rw-r--r-- 1 ubuntu ubuntu  576 Dec 30 18:16 id_rsa.pub

答案1

Match Group administrators
       AuthorizedKeysFile __PROGRAMDATA__/ssh/administrators_authorized_keys

将这些行设为注释行
