Proxy forward auth always granting access -> 200 #450

Describe the bug:

The forward auth endpoint always returns 200 even when hit using insomnia, a logged out incognito tab or using curl. In my traefik forward auth setup it also always grants access no matter what I do.
I've also tried to add a wildcard / domain with a group no user has been assigned to explicitly deny access but still 200.

To Reproduce:

1. hit the endpoint

Expected behavior:

Return 403 when not identified or no rule exists.

Postgres
