By default, Orchestrator permits access to workflows from Web service clients. However, the Orchestrator administrator can configure the server to deny connections from Web service clients.
If the Orchestrator administrator has disabled access to the server from Web service clients, the server only answers Web service client calls from the echo() and echoWorkflow() methods, for testing purposes.
The Orchestrator administrator enables and disables access to the server from Web service clients by setting a system property. For information about setting system properties, see Installing and Configuring VMware vCenter Orchestrator.
