Consider the following scenario. A client calls a Windows Communication Foundation (WCF) service. The WCF service is an orchestration that is published as a WCF service that uses a Request-Response receive port. This orchestration calls a second WCF service. When the second WCF service is called, the client’s credentials are not used. When this problem occurs, an event error that resembles the following is logged in the Application event log:
Event Type: Error Event Source: BizTalk Server 2006 Event Category: BizTalk Server 2006 Event ID: 5754 Description: A message sent to adapter "Adapter_Name" on send port "Send_Port_Name" with URI "URI" is suspended. Error details: System.ApplicationException: The context property http://schemas.microsoft.com/BizTalk/2003/system-properties#WindowsUser is not contained in the message context
Note This problem may also occur if you use Windows message security with a WCF receive location.
This problem occurs because the WCF adapter does not correctly promote the OriginatorSID context property. Therefore, the second WCF service call uses the orchestration host instance account instead of the original client credentials.
