Unable to add users using LDIF file in Osixia-OpenLdap image - docker

Question

I am trying to create an OpenLdap instance using image osixia/openldap:1.5.0 as a k8s service. Image works really well and the Ldap instance is also worked fine. However, when I'm trying to create users using user.ldif file, getting error. I created a configmap nameing users and mounted it to the k8s cluster.
