 {es} checks if the user is granted a specific action. If the user is assigned a role that grants a privilege, {es} uses the <<development-rbac-privileges, {kib} privileges>> definition to associate this with the actions, which makes authorizing users more intuitive and flexible programatically.
 
 Once we have authorized the user to perform a specific action, we can execute the request using `callWithInternalUser`.

-==== Legacy Fallback
-
-Users have existing roles that rely on index privileges to the `.kibana` index. The legacy fallback uses the `callWithRequest` method when the user doesn't have any application privileges. This relies on the user having index privileges on `.kibana`. The legacy fallback will be available until 7.0.
-
-Within the secured instance of the `SavedObjectsClient` the `_has_privileges` check determines if the user has any index privileges on the `.kibana` index:

-{kib} automatically detects that the request could be executed against `.kibana` using `callWithRequest` and does so.

-When the user first logs into {kib}, if they have no application privileges and will have to rely on the legacy fallback, {kib} logs a deprecation warning similar to the following:

-${username} relies on index privileges on the {kib} index. This is deprecated and will be removed in {kib} 7.0

-==== Reserved roles
-
-Ideally, the `kibana_user` and `kibana_dashboard_only_user` roles should only use application privileges, and no longer have index privileges on the `.kibana` index. However, making this switch forces the user to incur downtime if Elasticsearch is upgraded to >= 6.4, and {kib} is running < 6.4. To mitigate this downtime, for the 6.x releases the `kibana_user` and `kibana_dashbord_only_user` roles have both application privileges and index privileges. When {kib} is running >= 6.4 it uses the application privileges to authorize the user, but when {kib} is running < 6.4 {kib} relies on the direct index privileges.
