In order to access data in your data lake store, you must configure authentication with ADLS via Azure Active Directory (Azure AD). Azure uses Azure AD as a multi-tenant cloud-based directory and identity management service. For more information, refer to What is Active Directory.

You can configure authentication with ADLS by using either a client credential (analogous to a service principal) or a refresh token (associated with a user). We recommend that you use the simpler client credential method.
