Support backup configuration

**Feature request**
It would be great to have retry for auth.

**Use case**
Many users need this functionality for production deployments.

**Implementation idea**
Add a new config option `enable_retry` with default `false`.

Start by locating the configuration handling and authentication path in the repository. Trace where authentication failures are handled, then determine how the new enable_retry option should affect that flow; done means the option defaults to false and production authentication can retry when enabled.
