work, if the user first landed on `console-1.minio.example.org`, they must be redirected back to the same place after logging in at the OpenID provider's web-page. To ensure this, set the `MINIO_IDENTITY_OPENID_REDIRECT_URI_DYNAMIC=on` parameter - this lets MinIO set the redirect URL based on the "Host" header of the (initial login) request.

The **deprecated** parameter `MINIO_IDENTITY_OPENID_REDIRECT_URI` works similar to the `MINIO_BROWSER_REDIRECT_URL` but needs to include the `/oauth_callback`...
