Symptoms
Unable to upload files with SharePoint content Smart Object where SharePoint site authentication connection type is claims authentication. The Get files method works fine its just the Upload file method that does not work. The service instance uses the K2 service account as authentication method.
The following message is seen when this method is executed:
Error trying to execute (smospdocument).......
Diagnoses
The SharePoint Content broker is not supported using Claims-based Authentication.
Resolution
The best way to get around this is to use the Sharepoint 2013 service broker. OAuth authentication will be used on the Sharepoint 2013 service broker.
