Requests to wcf service are unauthorized
I want to use a wcf service in my asp.net application that uses integrated windows-authentication however all the requests to my Model.svc are 401 Unauthorized. If I change clientCredentialType="Windows" to clientCredentialType="Ntlm" every request is Unauthorized 2 times and the 3rd one is successful.
Here is my web.config:
<configuration>
<appSettings>
</appSettings>
<connectionStrings/>
<system.web>
<compilation debug="true" targetFramework="4.0" />
<authentication mode="Windows" />
</system.web>
<!--WCF Configuration-->
<system.serviceModel>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" aspNetCompatibilityEnabled="true"/>
<bindings>
<webHttpBinding>
<binding name="WebHttpBinding_IModel">
<security mode="TransportCredentialOnly">
<transport clientCredentialType="Windows" />
</security>
</binding>
</webHttpBinding>
</bindings>
<client />
<services>
<service behaviorConfiguration="ServiceBehavior" name="Model">
<endpoint address="" behaviorConfiguration="JsonBehavior" binding="webHttpBinding" bindingConfiguration="WebHttpBinding_IModel" contract="IModel">
<identity>
<dns value="localhost" />
</identity>
</endpoint>
</service>
</services>
<behaviors>
<endpointBehaviors>
<behavior name="JsonBehavior">
<webHttp />
</behavior>
&l开发者_开发知识库t;/endpointBehaviors>
<serviceBehaviors>
<behavior name="ServiceBehavior">
<serviceMetadata httpGetEnabled="true"/>
<serviceDebug includeExceptionDetailInFaults="true"/>
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
</configuration>
2 times unauthorized and third working is a part of the protocol. That is the way NTLM authentication works. Is this posing a problem? WCF is made to handle such scenarios, and so your WCF authentication call will work fine.
