Is User Provisioning to Active Directory the missing piece of the Entra identity puzzle?

In hybrid identity estates, cloud-led identity management often has to coexist with on-premises Active Directory. Line-of-business applications, access models and operational processes can still depend on AD. Even where Entra ID handles authentication, Conditional Access and governance, the source of authority for users can remain on-premises.

The missing piece has been user provisioning into Active Directory. Group provisioning allowed cloud-managed groups to be projected into AD for legacy access, but user objects remained harder to handle. Without a reliable way to provision users, organisations had to keep older identity management patterns in place, even when their strategic direction was cloud-first.

User provisioning from Entra ID to Active Directory gives organisations a more credible route to make Entra the place where user lifecycle decisions are made, while still supporting on-premises resources that cannot be retired overnight.

What user provisioning to AD enables

Direct provisioning of user objects from Entra ID to Active Directory using Microsoft Entra Cloud Sync.

Support for selective provisioning through scoping rules, so organisations can control which users are written back.

Organisational unit targeting, allowing provisioned users to be placed where they belong in AD rather than pushed into a generic location.

Password writeback support, so cloud-managed credentials can continue to work for on-premises authentication scenarios.

Provisioning and audit logs that give identity teams evidence of what happened, when it happened and why.

Where user provisioning changes the roadmap

User provisioning to Active Directory changes where identity ownership can sit. Instead of keeping user lifecycle decisions anchored to legacy directories, organisations can start moving more of that authority into Entra while still supporting AD-backed applications that remain in use.

That’s a more realistic path for most modernisation programmes.

AD rarely disappears in one move. Organisations need to reduce dependency in stages, avoid disrupting critical services and govern any change to identity authority properly. In that model, Entra becomes the place where lifecycle, access and assurance decisions are made, while AD remains available for the systems that still need it.

It also changes how organisations can manage legacy access. Instead of treating on-premises accounts as permanent, unmanaged exceptions, identity teams can govern them through the same lifecycle thinking used for cloud access.

• Joiner, mover and leaver (JML) processes can become more consistent
• Privileged or application-specific accounts can be brought under clearer control
• Guest or partner access to on-premises resources can be managed with more precision where Kerberos-based access is still required

The result is hybrid identity that’s easier to govern. Meaning we can establish:

• Where authority sits
• How access is issued
• How changes are evidenced
• How exceptions are contained

Decisions to make before shifting authority

Before changing how users are provisioned, identity teams need a clear view of the systems, processes and dependencies already shaping the estate.

Modernise hybrid identity without losing control

User provisioning to Active Directory gives organisations a stronger route out of legacy identity patterns. With the right AD model, application dependencies and transition design in place, identity teams can shift authority into Entra without forcing a hard break with systems that continue to depend on AD.

For organisations still running hybrid identity, this is the point to reassess the roadmap.

• Which users still need AD?
• Which applications still rely on it?
• Which lifecycle processes are being held back by older provisioning models?
• Where should Entra become the authority, with AD retained only where it still serves a clear purpose?

The organisations that get most value from this will treat it as part of a wider identity modernisation plan.

It gives identity teams a chance to reset where authority belongs. To determine who creates users, where lifecycle decisions are made, how access is governed, and where AD still has a defined role.

The aim is to keep hybrid identity transitional, with modernisation choices led by business need, risk and long-term identity strategy rather than by legacy constraints.
