[2008] Self-Hosted WCF Authenication

I've created a simple WCF Service Library which exposes a few functions. The WCF is Self-Hosted (exe) and everything runs fine.

However, currently there is no security on the WCF calls. Anyone on the network can access the WCFs calls. This is where I am struggling. I want to use Windows Authentication to a domain controller. Basically I want to say DOMAINNAME\USERNAME has access. But I am struggling understanding how to accomplish this.

This is the config file I have setup so far:

Code:

---

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
 
 
  <system.serviceModel>
       
    <bindings>
      <basicHttpBinding>
        <binding name="NewBinding0">
          <security>
            <transport clientCredentialType="Windows" />
          </security>
        </binding>
      </basicHttpBinding>
    </bindings>
    <services>
      <service behaviorConfiguration="BlackBerry_AD_WCF.ServiceBehavior"
        name="BlackBerry_AD_WCF.Service">
        <endpoint address="" binding="basicHttpBinding" bindingConfiguration="NewBinding0"
          contract="BlackBerry_AD_WCF.Service" />
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
        <host>
          <baseAddresses>
            <add baseAddress="http://servername.domain.xxx.com:8081/BlackBerry_AD_WCF" />
          </baseAddresses>
        </host>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="BlackBerry_AD_WCF.ServiceBehavior">
          <!-- 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="True" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>
 
  </configuration>

Basically I am looking to being able to specify which Active Directory Accounts/Groups can access this WCF function. Similiar to how you can do it in IIS.

Thanks for any help!
