ADFS 4.0:收到无效的客户端凭据

ADFS 4.0: Received invalid Client credentials

知道为什么会发生这种情况吗? 我们的 IT 将 ADFS 从版本 3 更新到版本 4。 更新后,我们的 ASP.NET 核心应用程序出现以下错误:

错误代码:

"Unhandled remote failure. (OAuth token endpoint failure: Status: BadRequest;
Body: {\"error\":\"invalid_client\",\"error_description\":\"MSIS9623: Received invalid Client credentials. The OAuth client is not configured to authenticate using passed in client credentials.\"};)"

要求:

 https://.../adfs/oauth2/authorize?client_id=d...4c&scope=&response_type=code&redirect_uri=https%3A%2F%2Flocalhost%3A44377%2F&state=CfDJ8...Og&resource=https%3A%2F%2Flocalhost%3A44377&redirect_url=https%3A%2F%2Flocalhost%3A44377

我试过也试过:

有人知道 "client credentials" 在这种情况下是什么意思吗?

当您通过向导在 ADFS 端配置应用程序时,您将获得一个 clientId。

这是您在请求中传递的 clientId。

检查您传递的 clientId 是否正确。

另请查看 ADFS 错误日志。

如果发送 "client_secret",ADFS 4.0 会抛出错误。 ADFS 3.0 忽略了该值。

UseOAuthAuthentication 始终发送 "client_secret"。我的 dirty 解决方案是拦截 http 请求并删除 "client_secret"。如果有人有更好的解决方案...

 if (securityService.IsOAuthEnabled)
 {

     HttpClientHandler clientHandler = new HttpClientHandlerInterceptor(){};
     var options = securityService.GetOAuthOptions();
     options.BackchannelHttpHandler = clientHandler;
     app.UseOAuthAuthentication(options);
 }

HttpClientHandlerInterceptor:

 public class HttpClientHandlerInterceptor : HttpClientHandler
 {
     protected override Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
     {
         if (request.Content is FormUrlEncodedContent)
         {
             var x = ((FormUrlEncodedContent) request.Content).ReadAsStringAsync().Result;
             var contenttype = request.Content.Headers.ContentType.MediaType;
             x = x.Replace("client_secret=will+be+ignored&", "");
             request.Content = new StringContent(x, Encoding.UTF8, contenttype);
         }
         return base.SendAsync(request, cancellationToken);
     }
 }

在您的请求字符串中注意:response_type=code

当我从 ConfigureAuth 函数中注释掉 Startup.Auth.cs 中的 UseOAuthe2CodeRedeemer 时,它缓解了手头的问题.

见下文:

        //    code_grant is present in the querystring (&code=<code>).
        //app.UseOAuth2CodeRedeemer(
        //    new OAuth2CodeRedeemerOptions
        //    {
        //        ClientId = AuthenticationConfig.ClientId,
        //        ClientSecret = AuthenticationConfig.ClientSecret,
        //        RedirectUri = AuthenticationConfig.RedirectUri
        //    }
        //);
