 # Overview - on-premises Active Directory Domain Services authentication over SMB for Azure file shares
-
-[Azure Files](storage-files-introduction.md) supports identity-based authentication over Server Message Block (SMB) using three different methods: 
-
-- On-premises Active Directory Domain Services (AD DS)
-- Azure Active Directory Domain Services (Azure AD DS)
-- Azure Active Directory (Azure AD) Kerberos for hybrid identities (preview)

 We strongly recommend that you review the [How it works section](./storage-files-active-directory-overview.md#how-it-works) to select the right AD source for authentication. The setup is different depending on the domain service you choose. This article focuses on enabling and configuring on-premises AD DS for authentication with Azure file shares.
