• ACLs
• Shared Key authorization
• Shared Access Signature (SAS) authorization

When RBAC is assigned to Data Lake Storage, this will always be at the top level of the account or the filesystem. This means that the user or the application will have access to everything that is stored in the account or in the container that access has been granted to.
