Hi all,
I want to do a very simple thing:

I want to create a user “admin” which will have some access privilege (read/write) to elastic logs (using Kibana) and another user name “devv” with only read privilege. I tried following the

Elastic.yml, kibana.yml , search guard 2 yml’s file. Please put the complete files conf if you can…
