Kibana unable to authenticate

[elasticbitz (Thomas Jenkins)]

I installed elasticsearch and kibana per the deb apt instructions on the site. All running fine, then added the xpack.security.enabled: true and discovery.type: single-node to the elasticsearch.yaml. Next I used the setup-passwords auto then added a user to the keystore. Updated the kibana.yaml with the kibaba_system password. restarted the services.

use the curl curl -XGET -u 'elastic:##########' http://localhost:9200/_cluster/health?pretty

and that results just fine.

however when I go to kibaba it says server not ready yet. check logs and see this:

What can I do to get this authenticated?

unable to authenticate user [admin]

It seems there are multiple users being used/tested here. Your curl command is using the elastic user, you mentioned updating the kibana_system, and the Kibana error seems you're using an admin user.

Can you ensure the kibana_system user is set for elasticsearch.username in the kibana.yml file. Then also verify those credentials work with curl?
