Install keycloak

helm install keycloak codecentric/keycloak
kubectl port-forward $KEYCLOAK_POD_NAME 8080

Bind it to Keycloak in the User Federation -> Add user storage provider -> ldap as below.

Why can't connect to ldap server? I login to the ldap pod to see the log but didn't find where is it.
