c# - LogonUser 失败，错误代码为 : 1326

Question

谁能帮我解决这个问题？我试图使用所需的凭据登录到 portal.microsoftonline.com，但它给我带来了错误。是我的网址有误还是什么？因为我试图模仿并赋予用户角色。谢谢，顺便说一句，我是新来的，请原谅我发布问题的方式。请查看错误所在的评论。

           throw new Exception("LogonUser failed with error code: " + ret);

        WindowsIdentity id = new WindowsIdentity(tokenHandle);
        CloseHandle(tokenHandle);
        return id;
     }
  }

xp_cmdshell 可能是通过代理帐户执行的。检查代理帐户是否具有正确的凭据。

在对象资源管理器中转到:

Security > Credentials > ##xp_cmdshell_proxy_account##

另外，检查用户是否有sys.xp_cmdshell的执行权限

在对象资源管理器中转到:

Databases > System Databases > master > Security > Users > [user] > Securables

授予权限的SQL:

use [master]
grant execute on xp_cmdshell to [domain\user];
