WCF. Use windows credentials on service side

Question

I have client on WPF and service. It's worked with security mode=None. But now I need on service side Windows credentials of the user who call service for making some action on Azure. So I changed configuration and now it's the following:

Service

<system.serviceModel>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
<client />
<bindings>
  <wsHttpBinding>
    <binding name="TrackingHoursServiceBinding" maxReceivedMessageSize="620000">

        <message establishSecurityContext="false" />
      </security> -->

    <!-- This is my changes  -->
      <security mode="Message">
        <message clientCredentialType="Windows" />
      </security>

On the service side, i try take credential using

System.Net.CredentialCache.DefaultCredentials

or

System.Net.CredentialCache.DefaultNetworkCredentials

But they return empty object.... How i can solve this issue?

Answer 1

After my test, I found that System.Net.CredentialCache.DefaultCredentials does not return null, whether on the client or server. Do you want to obtain username, password or domain through System.Net.CredentialCache.DefaultCredentials? If this is the case, it will return null because the instance DefaultCredentials returned by ICredentials cannot be used to view the user name, password, or domain of the current security context.
