Use WCF Consumer and REST Consumer with Kerberos

You can use Kerberos authentication in a WCF Consumer Activity or REST Conusmer Activity.

1. Configure the necessary activity.
2. Add the following sections to the activity's custom configuration.

<configuration>
  <system.serviceModel>
    <extensions>
      <behaviorExtensions>
        <add name="insertCustomHeaders" type="PNMsoft.Sequence.ServiceModel.Web.RestServiceInsertCustomHeadersExtension, PNMsoft.Sequence.ServiceModel, Version=7.0.0.0, Culture=neutral, PublicKeyToken=0a1a1b90c1c5dca1" />
      </behaviorExtensions>
    </extensions>
    <client>
      <endpoint name="RestServiceConsumer0webHttpBinding" binding="webHttpBinding" bindingConfiguration="WebHttpBinding" behaviorConfiguration="webBehavior" contract="RestServiceConsumer0">
        <identity>
          <servicePrincipalName value="HTTP/YourServiceName" />       // this is the Kerberos URL
        </identity>
      </endpoint>
