Documentation needs to be added on how to configure services so the App service can run in secure mode (i.e. can have a vault token generated for it)

I looked at recent stories related to sample app, looks like we always had issues with secure mode even with Levski code.
So yes, it could be configuration issue and sample app documentation needs to be updated for secure mode.
