How to configure Azure authentication?

I tried to activate Azure authentication.

I created my application on Entra. I set the 3 variables $AZUREAD_TENANT_ID, $OAUTH_CLIENT_SECRET and $OAUTH_CLIENT_ID.

But the login screen remains the same, with local login.

Anything else to configure?

PS: I deploy on Kubernetes with a heavily hacked https://gitlab.com/hermine-project/hermine-helm, but the variables are declared on the container.
