I get logstash and kibana to authenticate in multiuser just fine. What I am not sure about is what do you config the users for logstash and kibana under? I just assumed you create a group for them and then users under the users section. Elasticsearch does not startup then.
Example of what I have done:
response_if_req_forbidden: Sorry, your request is forbidden.
- name: Kibana Server login
- name: Logstash indexer login
- name: test user
Now how would one config users and groups?
