The current index authorization model in OpenSearch has a few quirks and weaknesses; these will be mostly noticeable when working in OpenSearch Dashboards or similar applications with users which have only limited access to indices. Thus, if you do not take care and forget to flip certain switches, you will encounter quite a few "Forbidden" errors in OpenSearch Dashboards. Over the past year, we have been working on a new index authorization concept for OpenSearch. The goal is a more logical and intuitive authorization model that provides a smoother and more predictable user experience.
This new approach is expected to be introduced as an optional feature in an upcoming OpenSearch release and is planned to become the default in OpenSearch 4.
