Authentication of [kibana] was terminated by realm [reserved]

Elastic Stack Kibana
1

Hi,

I converted a elasticsearch (6.3) standalone to a new cluster, after that kibana user is not authenticated and none of the reserved users are getting authenticated. And also i am not able to change the previously set passwords for the users when it was standalone. Also, getting license information could not be obtained from elasticsearch for the cluster.

[elk-master-node] Authentication of [kibana] was terminated by realm [reserved] - failed to authenticate user [kibana]

You haven't given us much information to go on, but from the symptoms it looks like your conversion from "standalone" to "new cluster" lost the security data.

  • How did you perform that conversion?
  • What is in your elasticsearch logs?
