One of our customers has created a workflow that contains an action to create a Form if certain criteria are met. When it hits this step, it always fails with the error "The caller was not authenticated by the service". The Job Owner for the workflow is a user that has user and security role of System Administrator. I can log in as this user and create the same Form manually without any issue at all.
There don't appear to be any errors reported in the Windows Event Log and I can't find anything directly related in IIS logs either.
I've Googled this error and there are quite a lot of cases of it occurring as a result of development/customization work, but I can't find any where it's occurred during a workflow.
Has anyone got any ideas on why this might be occurring?
Thanks
