If you don't use other realms ,the native realm is enabled by default as we say in our documentation:
https://www.elastic.co/guide/en/elasticsearch/reference/current/configuring-native-realm.html

Just remove the

xpack.security.authc.realms.native:  xpack:
  security:
    authc:
      realms:
        native:
          native1:
            order: 0

part entirely. For reference, the correct way to define the native realm ,if need be , would be like :

xpack:
  security:
    authc:
      realms:
        native:
          native1:
            order: 0

as also shown in the same doc above.

There is no point usually doing a curl to Kibana. You most probably want to use Kibana as a user interface so you'd normally access that with your browser.

Also, kibana is the user that Kibana uses to communicate to Elasticsearch, and should not be the user you use to authenticate to Kibana as an end user.

So, open up your browser, type http://<YOUR IP ADDRESS>:5601 , and when prompted for a username and password, use elastic as the username and the password you have set for the elastic user.

yes i did that too and its printing same message Kibana server is not ready yet in the web browser. Also i am getting this message before username and password. What else i can do.

should i do this .

Set up roles and users to control access to Elasticsearch.

For example, to grant John Doe full access to all indices that match the pattern events* and enable him to create visualizations and dashboards for those indices in Kibana, you could create an events_admin role and assign the role to a new johndoe user.

curl -XPOST -u elastic 'localhost:9200/_security/role/events_admin' -H "Content-Type: application/json" -d '{
  "indices" : [
    {
      "names" : [ "events*" ],
      "privileges" : [ "all" ]
    },
    {
      "names" : [ ".kibana*" ],
      "privileges" : [ "manage", "read", "index" ]
    }
  ]
}'

curl -XPOST -u elastic 'localhost:9200/_security/user/johndoe' -H "Content-Type: application/json" -d '{
  "password" : "userpassword",
  "full_name" : "John Doe",
  "email" : "john.doe@anony.mous",
  "roles" : [ "events_admin" ]
}'
49

Yes, at some point, but not for this exact problem you are seeing now.

Try using a different browser or try restarting your browser, or try clearing your cache and cookies. When you get prompted for username/password again, use the elastic user and its password.

Really thanx, now everything is working fine. :grinning::grinning::grinning:
