M requirement is to not allowed for some user to change the password FROM KIBANA UI. For example i have one user testUser with read-only access over dashboard; so that user (testUser) should not be able to change his password during seeing dashboard from kibana UI.
What i am usring:
Elastic search : elasticsearch-7.7.1-windows-x86_64
logstash : logstash-7.8.0
Kibana : kibana-7.2.0-windows-x86_64
The user is created through kibana UI and assigned the read-only dashboard role to see only visualization .
