- All sites must be using the **same** external IDP(s) if any.
- For [SSE-S3 or SSE-KMS encryption via KMS](https://min.io/docs/minio/linux/operations/server-side-encryption.html "MinIO KMS Guide"), all sites **must**  have access to a central KMS deployment. This can be achieved via a central KES server or multiple KES servers (say one per site) connected via a central KMS (Vault) server.
