OCI Search with OpenSearch now support role-based access control. With role-based access control, you can define and control what users can access and configure when connecting to an OpenSearch cluster.

For more information, see:

• Role-Based Access Control in OCI Search with OpenSearch
• OpenSearch - Users and roles

To use role-based access control with existing clusters that were created before today, you need to enable the feature, see Upgrading an Existing Cluster for Role-Based Access Control.
