Invalid login credentials

[StWiemann]

Hi, I was just trying to get this UI to run but I was having trouble with authentication.

I run a registry with Keycloak as Auth-Provider under docker.mydomain.com

I can easily log into that repository using docker login docker.mydomain.com providing my Keycloak-Credentials.

Now I configured Craneoperator to talk to my registry using the DNS:

      containers:
        - env:
            - name: REGISTRY_HOST
              value: docker.mydomain.com
            - name: REGISTRY_PORT
              value: '443'
            - name: REGISTRY_PROTOCOL
              value: https
            - name: ALLOW_REGISTRY_LOGIN
              value: 'true'
            - name: SESSION_SECRET
              value: RANDOM_STRING
            - name: REGISTRY_USERNAME
              value: SOME_USERNAME
            - name: REGISTRY_PASSWORD
              value: USER_PASSWORD
            - name: TITLE
              value: Super Registry UI
            - name: REGISTRY_ALLOW_DELETE
              value: 'true'

Crane starts and I get to the Frontpage saying "Error Loading Page - Registry requires authentication".
When I try to login I get "Invalid login credentials".

Logs from Craneoperator:

Does this not support the registry-login with OAuth? Even though I don't really know how the authentication mechanism behind the registry would effect this.

Thank you for any help.
