When an Ingress explicitly enables BasicAuth or DigestAuth through the supported `nginx.ingress.kubernetes.io/auth-type` and `auth-secret` annotations, but the referenced auth Secret cannot be resolved or parsed, Traefik logs the resolution error, skips installing the authentication middleware, and still emits a router to the backend service. A route that operators intended to protect is therefore published to the data plane without its authentication control, allowing unauthenticated access to the backend.
