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.
When running multiple tenants of Kibana by changing the
kibana.index in your
kibana.yml, you cannot use
kibana_admin to grant access. You must create custom roles that authorize the user for that specific tenant. Although multi-tenant installations are supported, the recommended approach to securing access to Kibana segments is to grant users access to specific spaces.
