General Availability: Support for Linux clients to use identity-based access to Azure file shares over SMB

Published date: April 19, 2023

Azure Files now supports Linux clients to use identity-based authentication over Server Message Block (SMB). Previously only Windows clients were supported by Azure Files.  

In order to leverage identity based authentication and authorization, the clients need to be domain joined to one of the following Domain Services:

  1. On-premises Active Directory Domain Services (AD DS)
  2. Azure Active Directory Domain Services (Azure AD DS).

Azure Active Directory (Azure AD) Kerberos for hybrid identities is NOT supported yet for Linux clients.

This capability will enable customers who are moving a mix of Windows and Linux environments to cloud to have a consistent identity system across both Windows and Linux workstations.
