 The following diagram depicts on-premises AD DS authentication to Azure file shares over SMB. The on-premises AD DS must be synced to Azure AD using Azure AD Connect sync or Azure AD Connect cloud sync. Only [hybrid user identities](../../active-directory/hybrid/whatis-hybrid-identity.md) that exist in both on-premises AD DS and Azure AD can be authenticated and authorized for Azure file share access. This is because the share-level permission is configured against the identity represented in Azure AD, whereas the directory/file-level permission is enforced with that in AD DS. Make sure that you configure the permissions correctly against the same hybrid user.

 2. All users that exist in Azure AD can be authenticated and authorized. The user can be cloud-only or hybrid. The sync from Azure AD to Azure AD DS is managed by the platform without requiring any user configuration. However, the client must be joined to the Azure AD DS hosted domain. It can't be Azure AD joined or registered. Azure AD DS doesn't support non-cloud VMs (i.e. user laptops, workstations, VMs in other clouds, etc.) being domain-joined to the Azure AD DS hosted domain.
