Azure Files Entra-Only Identities Now GA

3 min read

Summary

Microsoft has announced general availability of Entra-Only identities for Azure Files SMB, allowing organizations to use native Microsoft Entra ID authentication without Active Directory, hybrid sync, or managed domain controllers. The update simplifies cloud-native file access, strengthens Zero Trust alignment, and reduces operational overhead for Azure Virtual Desktop, FSLogix, and general file-sharing scenarios.

Introduction

Microsoft has made Entra-Only identities for Azure Files SMB generally available, removing a major barrier for organizations moving file services fully into Azure. For IT teams, this means secure SMB access using native Microsoft Entra ID authentication without relying on on-premises Active Directory, Entra Connect sync, or managed domain controllers.

This is a significant step toward a simpler, more secure, and truly cloud-native identity model for file shares.

What’s new

Native Entra ID authentication for Azure Files SMB

Organizations can now authenticate users and devices directly with Microsoft Entra ID for Azure Files SMB access. Azure Files uses Entra ID as the Kerberos Key Distribution Center, allowing clients to request Kerberos tickets directly from Entra.

No Active Directory dependency

This GA release eliminates the need for:

  • On-premises Active Directory
  • Hybrid identity sync
  • Managed domain controllers
  • VPN or complex network connectivity for file access

Portal-based NTFS permissions management

Admins can now configure granular NTFS ACLs for Entra-Only and hybrid users and groups directly in the Azure portal. This removes the need for domain-joined management machines or legacy administration tools.

Expanded RBAC support

Share-level RBAC assignment for specific Entra-only users and groups is also rolling out in limited regions, improving authorization options for Azure Files deployments.

Better support for AVD and remote work

The feature is especially important for Azure Virtual Desktop environments using FSLogix profile containers on Azure Files Premium. Built-in B2B support also allows external users to access desktops and profiles with their existing identities.

Why this matters for IT admins

For Azure administrators, this release reduces identity and infrastructure complexity while improving security posture. Teams can modernize file access using a Zero Trust-friendly model and avoid maintaining legacy domain services just to support SMB shares.

Key benefits include:

  • Lower operational overhead
  • Simpler cloud-native deployments
  • Easier support for remote and distributed users
  • Consistent identity-based access controls
  • Reduced dependency on legacy infrastructure

It also supports coexistence with hybrid identity setups, which is useful for organizations transitioning away from Active Directory over time.

Next steps

If you manage Azure Files, AVD, or cloud migration projects, now is a good time to:

  • Review Azure Files SMB authentication settings
  • Evaluate Entra-Only identities for new deployments
  • Test portal-based NTFS ACL management
  • Assess AVD and FSLogix scenarios for cloud-native identity modernization
  • Check regional availability for expanded RBAC support

For organizations pursuing a full Azure-native architecture, this GA release makes Azure Files a much stronger option for secure, modern file access.
