HTTP请求未经授权使用客户端身份验证方案“Basic”。从服务器收到的身份验证标头是“Negotiate，NTLM”

Question

我正在尝试使用以下设置连接到服务。

<bindings>
  <basicHttpBinding>
    <binding name="EngineSoap" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="2147483647" maxBufferPoolSize="524288" maxReceivedMessageSize="2147483647" messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true">
      <readerQuotas maxDepth="32" maxStringContentLength="2147483647" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384"/>
      <security mode="TransportCredentialOnly">
        <transport clientCredentialType="Basic" proxyCredentialType="None" realm=""/>
        <message clientCredentialType="UserName" algorithmSuite="Default"/>
      </security>
    </binding>
  </basicHttpBinding>
</bindings>
<client>
  <endpoint address="http://addressToService" binding="basicHttpBinding" bindingConfiguration="EngineSoap" contract="TRIMAPI.EngineSoap" name="EngineSoap" />
</client>

我得到的错误如下：

The HTTP request is unauthorized with client authentication scheme 'Basic'. The authentication header received from the server was 'Negotiate,NTLM'. ---> System.Net.WebException: The remote server returned an error: (401) Unauthorized.
   at System.Net.HttpWebRequest.GetResponse()
   at System.ServiceModel.Channels.HttpChannelFactory.HttpRequestChannel.HttpChannelRequest.WaitForReply(TimeSpan timeout)
   --- End of inner exception stack trace ---

   at System.ServiceModel.Channels.ServiceChannelProxy.InvokeService(IMethodCallMessage methodCall, ProxyOperationRuntime operation)
   at System.ServiceModel.Channels.ServiceChannelProxy.Invoke(IMessage message)

我试图将clientCredentialType =“Basic”更改为“Windows”和“Ntlm”但是徒劳无功。我无法将安全模式设置为“TransportCredentialOnly”以外的任何内容，因为该服务不使用SSL。

此外，用户名是'domain \ username'。

我错过了什么？

Answer 1

clientCredentialType需要是Ntlm而不是Basic

<bindings>
  <basicHttpBinding>
    <binding name="EngineSoap">
      <security mode="TransportCredentialOnly">
        <transport clientCredentialType="Ntlm" proxyCredentialType="None" realm=""/>
      </security>
    </binding>
  </basicHttpBinding>
</bindings>

如果是HTTPS / SSL连接，则将TransportCredentialOnly更改为Transport。有关详细信息，请参阅<transport> of <basicHttpBinding>。

Answer 2

未启用托管服务的服务器（IIS）上的基本身份验证。启用它为我解决了问题。
