Azure Files Drops On-Prem AD Dependency: Entra-Only Identities Now Generally Available

Microsoft today announced the general availability of Entra-Only identities for Azure Files SMB, enabling cloud-native identity authentication without requiring any on-premises Active Directory. This marks a significant shift for enterprises migrating to fully cloud-based storage.

With this release, organizations can now authenticate users and devices directly through Microsoft Entra ID, eliminating the need for Active Directory, hybrid synchronization, or managed domain controllers. The move accelerates cloud adoption by removing a key architectural blocker.

Key Capabilities

Simplified operations: Azure Files now supports native Entra ID authentication with Intune client integration, reducing identity lifecycle management and compliance overhead. No VPNs or domain setups are required.

Coexistence with hybrid setups: The feature works alongside existing hybrid identities, allowing phased migration away from on-premises Active Directory.

Remote access from anywhere: Entra-joined clients can access file shares securely from any location, supporting seamless remote work without identity duplication.

MacOS support in limited preview: Starting with this release, MacOS clients joined via Platform SSO can also access Azure Files with Entra-based authentication.

Quote from Microsoft

“With Entra-Only identities, we are delivering a truly cloud-native identity experience for Azure Files,” said Jane Doe, Vice President of Azure Storage at Microsoft. “This removes the last major hurdle for customers who want to modernize their storage, compute, and identity stacks while aligning with Zero Trust principles.”

Background

Previously, Azure Files SMB access required either Active Directory Domain Services (AD DS) or Azure AD Domain Services, forcing organizations to maintain hybrid identity infrastructure. This dependency often stalled cloud migration projects, especially for Windows-based workloads and virtual desktop environments.

The new Entra-Only model directly addresses that bottleneck. By allowing cloud-only identities, Microsoft aligns Azure Files with modern security frameworks and reduces ongoing maintenance costs for IT teams.

What This Means

For virtual desktop infrastructure (VDI): Azure Virtual Desktop customers can now manage FSLogix profiles using Entra-Only identities, including built-in B2B support for external partners—no duplicate accounts needed.

For general workloads: Enterprises migrating on-premises Windows servers to Azure can retain native SMB compatibility while eliminating domain setup, VPN complexity, and hybrid sync overhead.

For security: The zero-trust compliance strengthens overall security posture by enforcing identity-based access without relying on legacy on-premises authentication methods.

Industry Reaction

Analysts note that this move simplifies one of the most common pain points in cloud file storage. “It's a game-changer for organizations aiming for a fully cloud-native architecture,” said John Smith, Principal Analyst at CloudInsights. “By removing the AD dependency, Microsoft makes Azure Files a more compelling option for enterprises.”

How to Get Started

Enable Microsoft Entra Kerberos authentication via the Azure Portal or PowerShell. The feature is available in all Azure regions where Azure Files is supported. For detailed instructions, see our step-by-step guide.

Note: MacOS support remains in limited preview; interested customers can apply through the Azure Files preview program.

Conclusion

The Entra-Only identity launch represents a major step toward cloud-native storage. With simplified operations, enhanced security, and broader platform support, Azure Files is now positioned as a leading solution for enterprises transitioning to the cloud.
