I did a fresh install of opensearch under linux for systemd. During installation I recovered the randomly generated admin password.
Now I realize that there is a user kibanaserve with the default password kibnaserve without my knowledge.
Do you know why this user has been created?
The kibnaserve user is a system user used by OpenSearch Dashboards to communicate with OpenSearch nodes (please keep in mind: the kibanaserver user is crucial for the internal communication between OpenSearch Dashboards and the OpenSearch cluster.)
