verify_claims errors #546
Description
When using verify claims, I don't see a way to return an error explaining why the verification failed to inform users why they were denied access. I'm following the instructions at https://mozilla-django-oidc.readthedocs.io/en/stable/installation.html#advanced-user-verification-based-on-their-claims.
How can I provide feedback to indicate to users why they were denied access? If there isn't something already in place, I would like to be able to raise an exception here that is converted to an error message that can be presented in the UI.
