We needed a PowerShell Function to call from Winshuttle Workflow that would ensure the user was in SharePoint after a SQL load to the aspnetdb. The trick appears to be using "AllowUnsafeUpdates," similar to what many others have posted with their C# code. There were also some items noted in the config files where the machine.config required the FBA connection string in order for the PowerShell to work.
Are you a user?
