Recently, I have configured ELK stack with x-pack security enabled. it is working fine now, now I wanted to extend security by integrating kibana with ldap. Could you help us how to integrate ldap with kibana. The current version of EFK is 7.5.2 and I created PEM encoded certificates as per document for xpack security with some CN. Is there any relation between PEM encoded certificates and LDAP configuration and authentication.
