The Elastic Stack comes with the
kibana_admin built-in role, which you can use to grant access to all Kibana features in all spaces. To grant users access to a subset of spaces or features, you can create a custom role that grants the desired Kibana privileges.
When you assign a user multiple roles, the user receives a union of the roles’ privileges. Therefore, assigning the
kibana_admin role in addition to a custom role that grants Kibana privileges is ineffective because
kibana_admin has access to all the features in all spaces.
