Impersonation when using SmartObjectClientServer?

I'm trying to use the "Process Data Audit" SmartObject to show the history of a particular data field in an ASP.NET application:


SmartObjectClientServer smartObjectServer = new SmartObjectClientServer();
smartObjectServer.CreateConnection();
smartObjectServer.Connection.Open(Settings.SmartObjectServerConnectionString);
SmartObject smartObject = smartObjectServer.GetSmartObject("Process_Data_Audit");
smartObject.MethodToExecute = "List";
smartObject.Properties["ProcInstID"].Value = processInstanceId.ToString();
smartObject.Properties["Data_Name"].Value = k2FieldName;
SmartObjectList results = smartObjectServer.ExecuteList(smartObject);


This works fine when I run it from a console app or the .NET application.


Now I want to move this code to a WCF service (hosted as a Managed Windows Service) for use with AJAX-style operations.  The same code throws SmartObjectException exceptions in this scenario with the following details:


Service: WorkflowReportingService
Service Guid: ef7310e5-b14f-464d-b0f3-a37d6c367620 
Severity: Error 
Error Message: Object reference not set to an instance of an object. 
InnerException Message:


I'm guessing this has something to do with impersonation and the service account the WCF service runs as since the same code works find in other scenarios.  My problem is that I can't seem to find an ImpersonateUser() method in the SourceCode.SmartObjects namespace.


Advice on impersonation (or other workarounds) is appreciated.

You would not do the impersonation in the SourceCode.SmartObjects name space.  you would need to do the impersonation with the connectionstringbuilder when connecting to the K2 server.


 


I am looking for a code sample, but if someone has one please post.

I am looking for a code sample, but if someone has one please post.

Thanks for the advice.  Here is a code sample I came up with:


SCConnectionStringBuilder connectionString = new SCConnectionStringBuilder(Settings.SmartObjectServerConnectionString);
connectionString.UserID = @"domainuser";


connectionString.Password = @"pass";


SmartObjectClientServer smartObjectServer = new SmartObjectClientServer();
smartObjectServer.CreateConnection();
smartObjectServer.Connection.Open(connectionString.ConnectionString);
SmartObject smartObject = smartObjectServer.GetSmartObject("Process_Data_Audit");
smartObject.MethodToExecute = "List";
smartObject.Properties["ProcInstID"].Value = processInstanceId.ToString();
smartObject.Properties["Data_Name"].Value = k2FieldName;
SmartObjectList results = smartObjectServer.ExecuteList(smartObject);


What I don't know is what permissions the supplied user needs to have to pull this data correctly.
