django.db.utils.OperationalError: GSSAPI authentication not supported

I imagine Django 3.1 is the same story?
my environment:
python:3.8-alpine image (3.8.5)
Django==3.0.9
django_cockroachdb==3.0.1

I'm not familiar with GSSAPI but as far as I can tell, this error is coming from the database. You'll need to explain why you believe django-cockroachdb is at fault.

@timgraham I'm testing with 2.2 which I know works with GSSAPI and I'm getting similar error. This is likely something I'm doing wrong, let's keep this open for a bit more while I investigate.

everything works across 2.2, 3.0 and 3.1, thank you.
