Two issues are pressing:

1. UserLifecycle does not support multiple error messages per pop. Having an array of error messages is not allowed. This can be easily fixed on the Openconext-user-lifecycle side. https://github.com/OpenConext/OpenConext-user-lifecycle/pull/62
2. Stepup-MIddleware is moaning to loudly when an identity is not found. This now results in a FAILED response from StepUp. That's a bit to severe. When an identity is not using StepUp, it should simply respond with an OK with empty data.
