Hi  
I am using a basic license and trying to enable security on a single node ELK cluster . to enable security i have added the below lines in elasticsearch.yml

```auto
xpack.security.enabled: true
discovery.type: single-node

```

In kibana.yml i have enabled the following lines

```auto
elasticsearch.username: "kibana_system"
elasticsearch.password: "pass"

```

but i am getting the below error in kibana log and the UI is not accessible

```auto
[security_exception]: missing authentication credentials for REST request [/_nodes?filter_path=nodes.*.version%2Cnodes.*.http.publish_address%2Cnodes.*.ip]"}

```

I have tried using the below credentials in kibana.yml but then also i am getting the same error:

```auto
xpack.monitoring.elasticsearch.username: "kibana_system"
xpack.monitoring.elasticsearch.password: "kibanapassword"

```

Any help on the above will be really great ..

You need to first set the password for the builtin users ( see [here](https://www.elastic.co/guide/en/elasticsearch/reference/current/configuring-security.html) ), as `kibana_system` is a builtin user. Then you'd need to add that password as `elasticsearch.password` in your kibana.yml.
