WCF Streaming on service with Windows Authentication Endpoint - wcf

Question

I have a WCF service with two endpoints defined by the configuration file below:
<system.serviceModel>
<services>
<service name="SyncService" behaviorConfiguration="SyncServiceBehavior">
<endpoint name="Data" address="Data" binding="basicHttpBinding" bindingConfiguration="windowsAuthentication" contract="ISyncService"/>
<endpoint name="File" address="File" binding="basicHttpBinding" bindingConfiguration="httpLargeMessageStream" contract="ISyncService"/>
<endpoint address="mex" binding="webHttpBinding" bindingConfiguration="windowsAuthentication" contract="IMetadataExchange"/>
</service>
</services>
<bindings>
<basicHttpBinding>
<binding name="httpLargeMessageStream" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" transferMode="Streamed" messageEncoding="Mtom" />
<binding name="windowsAuthentication" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647">
<security mode="TransportCredentialOnly">
<transport clientCredentialType="Windows" proxyCredentialType="None" realm=""></transport>
<message algorithmSuite="Default" clientCredentialType="UserName"/>
</security>
</binding>
</basicHttpBinding>
<webHttpBinding>
<binding name="windowsAuthentication">
<security mode="TransportCredentialOnly">
<transport clientCredentialType="Windows"></transport>
</security>
</binding>
</webHttpBinding>
</bindings>
<behaviors>
<serviceBehaviors>
<behavior name="SyncServiceBehavior">
<serviceMetadata httpGetEnabled="true"/>
<serviceDebug includeExceptionDetailInFaults="true"/>
<dataContractSerializer maxItemsInObjectGraph="2147483647"/>
</behavior>
</serviceBehaviors>
</behaviors>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true"></serviceHostingEnvironment>
</system.serviceModel>
I want to use windows authentication for the Data endpoint, but have recently discovered that you cannot use windows authentication for streaming over HTTP. I removed the security element for the File endpoint, but still get the following error:
HTTP request streaming cannot be used in conjunction with HTTP
authentication. Either disable request streaming or specify anonymous
HTTP authentication. Parameter name: bindingElement
Is it possible to have two endpoints on the same service use different authentication methods like this? Why can't I use windows authentication for streaming?
I have also tried what was suggested in this thread, but to no avail:
Which authentication mode of basichhtpbinding can be used to secure a WCF Service using Streaming?

Unfortunately this is not supported.
