## Concepts

- All Buckets on MinIO are always in one of the following states: unversioned (the default) and all other existing deployments, versioning-enabled, or versioning-suspended.

- **Removing a site** is not allowed from a set of replicated sites once configured.
- All sites must be using the **same** external IDP(s) if any.

## Use the `scopes` { #use-the-scopes }

The parameter `security_scopes` will be of type `SecurityScopes`.

It will have a property `scopes` with a list containing all the scopes required by itself and all the dependencies that use this as a sub-dependency. That means, all the "dependants"... this might sound confusing, it is explained again later below.
