The authentication schemes configured on the host ('Basic')

Question

When I log in into wcf localhost/Service1.svc I get Error:

The authentication schemes configured on the host ('Basic') do not allow those configured on the binding 'BasicHttpBinding' ('Anonymous'). Please ensure that the SecurityMode is set to Transport or TransportCredentialOnly. Additionally, this may be resolved by changing the authentication schemes for this application through the IIS management tool, through the ServiceHost.Authentication.AuthenticationSchemes property, in the application configuration file at the element, by updating the ClientCredentialType property on the binding, or by adjusting the AuthenticationScheme property on the HttpTransportBindingElement.

Web.Config

<?xml version="1.0"?>
<configuration>
  <system.web>
    <compilation debug="true" targetFramework="4.0" />
    <authentication mode="Windows" />
    <customErrors mode="Off"/>
  </system.web>
  <system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
          <serviceMetadata httpGetEnabled="true"/>
          <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
          <serviceDebug includeExceptionDetailInFaults="false"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
  </system.serviceModel>
  <system.webServer>
    <modules runAllManagedModulesForAllRequests="true">
      <add name="BasicAuthHttpModule"
        type="WCF_Customer_RentalObject.BasicAuthHttpModule, WCF_Customer_RentalObject"/>
    </modules>
  </system.webServer>
</configuration>

Do you know what I have to do?

When I add this:

<bindings>
  <basicHttpBinding>
    <binding> <!--Notice, no name attribute set-->
      <security mode="TransportCredentialOnly">
        <transport clientCredentialType="Windows" />
      </security>
    </binding>
  </basicHttpBinding>
</bindings>

I get another error:

The authentication schemes configured on the host ('Basic') do not allow those configured on the binding 'BasicHttpBinding' ('Negotiate'). Please ensure that the SecurityMode is set to Transport or TransportCredentialOnly. Additionally, this may be resolved by changing the authentication schemes for this application through the IIS management tool, through the ServiceHost.Authentication.AuthenticationSchemes property, in the application configuration file at the element, by updating the ClientCredentialType property on the binding, or by adjusting the AuthenticationScheme property on the HttpTransportBindingElement.

1. Suggested client config:

<bindings>
  <basicHttpBinding>
    <binding name="basicEndpoint">
      <security mode="Transport" >
        <transport clientCredentialType="Basic"
                   proxyCredentialType="None"
                   realm="" />
      </security>
    </binding>
  </basicHttpBinding>

May be mode="TransportCredentialOnly"> is OK
but <transport clientCredentialType="Windows" /> is probably not the best

2. Pass the credentials :

HelloServiceClient client = new HelloServiceClient();
client.ClientCredentials.UserName.UserName = userName;
client.ClientCredentials.UserName.Password = password;
String msg = client.SayHello(userName);

Hope it helps
