I am not able to access the Coordinator API : Root path: /druid-ext/basic-security/authentication

I want to setup setup druid basic security. I followed the instruction as below link:

http://druid.io/docs/latest/development/extensions-core/druid-basic-security.html

But I am not able to understand the below point.

“To use these APIs, a user needs read/write permissions for the CONFIG
resource type with name “security”.”

Also, I am not able to access the Coordinator API as below:

Root path: /druid-ext/basic-security/authentication

For more information I hereby attached my common.runtime.properties config file.
