This is an example of a workflow that contains a call to a secure Web service that runs behind HTTPS and requires user to authenticate. The first thing you can expect to see is a pop up dialog asking if you trust the Web service to be invoked over HTTPS. You can use testuser/testpasswd as username and password for authentication when running the workflow. To see where the security is being configured, right-click the service in the diagram and select "Configure security" from the menu.
