I'm trying to setup basic auth for my test ingress rule and I couldn't figure out why it doesn't work. I can still access the site without a password prompt.

Versions: EKS 1.16
Helm chart nginx-ingress-0.5.2
Nginx version 1.7.2(also tried with 1.7.0 and latest)

basic-auth secret content:

kubectl get secret basic-auth -o yaml
apiVersion: v1
data:
  auth: Zm9vOiRhcHIxJHZ4RzVoc1VQJE1KZmpNcEQ2WHdPV1RaaTFDQUdlYTEK
kind: Secret
metadata:
  creationTimestamp: "2020-07-02T04:46:58Z"
  name: basic-auth
  namespace: default
  resourceVersion: "8252"
  selfLink: /api/v1/namespaces/default/secrets/basic-auth
  uid: e3b8a6d3-009b-4a4c-ad8b-b460381933d8
type: Opaque

Ingress rule:

Ingress rule:
apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
  name: hello-world-ing
  annotations:
    kubernetes.io/ingress.class: "nginx"
    # type of authentication
    nginx.ingress.kubernetes.io/auth-type: basic
    # name of the secret that contains the user/password definitions
    nginx.ingress.kubernetes.io/auth-secret: basic-auth
    # message to display with an appropriate context why the authentication is required
    nginx.ingress.kubernetes.io/auth-realm: 'Authentication Required - foo'
spec:
  rules:
  - host: test.*****.com
    http:
      paths:
      - backend:
          serviceName: docker-hello-world-svc
          servicePort: 8088  

Also I haven't found basic-auth section within nginx controller configuration file for hello-world-ing service:

kubectl -n nginx-ingress exec -it dev-nginx-ingress-6d5f459bf5-s4qqg -- cat /etc/nginx/conf.d/default-hello-world-ing.conf  
***
	location / {

		client_max_body_size 1m;
		proxy_set_header Host $host;

		proxy_buffering on;
		proxy_pass http://default-hello-world-ing-***-docker-hello-world-svc-8088;
	}

I haven't found anything suspicious in controller logs.
