Best practices for hybrid Active Directory automation

Modern organizations are complex, evolving and often balancing legacy systems with emerging technologies. These scenarios are reflected in their Microsoft directory environments, where it’s common to find both AD domains and Entra ID tenants.

This hybrid reality is here to stay. It calls for a similarly diverse strategy for on-premises and cloud identity management and protection where there’s a consolidated view across all directories, with synchronized actions, fine-grained delegation and consistent security processes. Otherwise, it can easily turn native tools and workloads into heavy burdens for busy service desks and administrators. That’s why, instead of manually enforcing privileges and granting access, hybrid AD automation can lighten the load as a key best practice.

Why you need hybrid AD automation

Hybrid identity environments can be difficult to manage due to the many AD domains and Entra ID and M365 tenants, each of which require separate consoles. This can result in inconsistent policies and policy adherence, not to mention the resource burden.

Centralization and standardization should be the goal for AD deployments to ensure hardening and fine-grained visibility across the business. This can soon put pressure on AD administrators, especially at the enterprise level where roles may evolve, and where joiners, movers and leavers number in the hundreds or thousands each year. To add to the pressure, there’s often a demand for rapid deployment and product shipping, which can pose tough questions to developers who may not have the necessary identity security answers.

These risks are compounded when each administrator has their own way of working, applying policies, and setting permissions and privileges. This leads to inconsistencies in how a hybrid Microsoft directory environment is managed, with greater challenges coming from the lack of real-time visibility across on-premises and cloud infrastructures.

What’s more, management expertise is more likely to be retained by individuals instead of being scaled across the business. This leads to gaps in knowledge among teams, resulting in potential silos and vulnerabilities across the attack surface.

There may be accounts created for one-off projects, test accounts or redundant legacy applications. If there is no assigned owner, these can become orphaned accounts, left to stand as potential routes into unguarded networks. Any breach using these types of unprotected credentials can often remain undetected, with attackers using privileges to elevate permissions and continue lateral movement within the environment.

One example was a botnet of 130,000 compromised devices in early 2025. A threat actor used the botnet to exploit Microsoft 365 accounts with basic authentication for sign-in processes. The lack of advanced authentication meant attackers could “avoid MFA enforcement as well as potentially also bypass conditional access policies.” Microsoft is retiring basic authentication (scheduled for completion by April 30, 2026), but the incident acts as a reminder to IT and security leaders of how unsecured identities can lead to continuously undetected, unauthorized access.

Increased account management demands would normally mean an increase in manual efforts. Automation offers another way to manage accounts without relying on huge investment or scaling up resources to a potentially unsustainable level. Hybrid AD automation can be used to streamline repetitive tasks. It also removes the risk of mistakes that can occur when humans are asked to complete routine tasks on a continuous basis, especially when meeting enterprise-sized and always-on workflow requirements around new starters, leavers and role-changers.

Impact of automated workflows for AD in the enterprise

Various studies since the 1940s have found that ”the central nervous system, regardless of species, cannot sustain attention for an indefinite period of time; the focus of attention appears to be temporally limited.” These types of lapses can be seen as a feature rather than a bug – attributed to how brains are wired. Of course, IT workers aren’t immune to this, which is why the nature of repetitive work comes with risks.

Workers naturally slip into a form of autopilot rather than remaining in a constant state of vigilance, and errors can creep in. That could mean not updating an employee’s changing role or end of employment, not noticing some anomalous network activity, or entering an incorrect value into a database. This lack of automation and synchronization with reliance on manual input, plus the lack of visibility across on-premises and cloud infrastructures, poses threats to IT environments.

For example, the Cloudflare outage in late 2025 was attributed to “routine maintenance” and a “change deployed by our team.” By automating repeatable processes, enterprises can minimize exposure to the threat of a human to continuously manage the same environment for extended periods of time. Plus, automating workflows offers potential gains across the entire business, assuming there’s a consolidated view of identities.

Securing the business for joiners, movers and leavers

Onboarding and offboarding simplification can reduce risk and improve efficiency and accuracy. IT and HR leaders can manage identity accounts from their HCM solution using their AD or Entra ID.

Onboarding and offboarding can happen automatically, as part of predefined workflows. When employee details are added to the HCM, this can generate account creation and relevant resources within AD, from email to local drives. Meanwhile, Entra ID can allow or deny dynamic group membership based on rules for the identity’s attributes.

Any risks with leavers, such as those whose employment is terminated on bad terms, can be mitigated by triggers that lock access or prevent data exfiltration. Within Entra ID, this can involve conditional access triggers: Set these to block and revoke sign-ins, MFA methods, and group memberships.

Role changes can be actioned automatically

Longer-term employees may not leave, but they are likely to change roles, especially if they’re involved in short-term projects or sprints. Asking administrators to manually update role changes and grant access to new resources isn’t practical when workers reportedly use an average of 11 apps a day.

Within Entra ID, directory and security administrators can make use of Lifecycle Workflows. Alongside features for joiners and leavers, there are multiple identity governance capabilities for movers. Access and authorization can be automated using tasks and execution conditions. User and extended attributes can be used for complex workflows and scenarios typical in larger organizations. This allows administrators to apply a holistic approach for individuals instead of workflows based on group attributes.

Further hardening comes from AD features, in particular for elevated roles and privileges that offer greater threats and opportunities to attackers. Any expired administrative role should have its active assignments removed, and any activation or reactivation attempts should be automatically blocked.

This reduces the risks that can appear when an employee changes their duties but retains privileges from a previous position in the company. Administrators can adopt a Principle of Least Privilege (PoLP) approach, with access available at the right time.

Just-in-Time access

Lifecycle Workflows can be combined with Entra ID’s PIM capabilities to control who has access to resources at any time. Further protection comes from implementing conditional access rules. For example, allowing access from approved devices in specific regions at certain times of the day. Any activity outside these parameters can either trigger an extra authorization step, to allow genuine users to gain access, orcan simply block the attempt.

Entra ID also limits the assignments to other administrators, helping to minimize the risks from an attacker gaining access and granting excessive privileges to other malicious actors. The business can then allow access to designated users at the times they need it. This allows for less reliance on system administrators to manually approve, reject or revoke access. Meanwhile, employees can harness the insights they need, when they need the information, without a lengthy login experience.

Password management

Microsoft also offers capabilities for hybrid setups that help protect against bad actors. For example, by “setting smart lockout policies in Microsoft Entra ID appropriately, attacks can be filtered out before they reach on-premises AD DS.”

Employees can be reminded to change passwords at set intervals, sometimes for compliance reasons. For example, PCI DSS specifies that when passwords or phrases are the sole authentication factor for user access, they must be changed “at least once every 90 days.” (pdf).

Reminders can be triggered based on accounts that show no logins for an extended period of time or for those that have passwords with no expiry-related management. With AD, you can configure fine-grained password policies for different users within the same domain. Configuration policies can be based on privileges and can apply only to global security groups and user objects.

Hybrid AD automation across on-premises and cloud infrastructures

These hybrid AD best practices allow businesses to implement consistent, standardized and responsive identity account management and control, though this control does rely on a consolidated view across on-premises and cloud. The identity automation can then be scaled and synchronized without risks that come from manual configuration, such as inconsistent setups, siloed knowledge and errors stemming from repetition fatigue.

The workflows can be adapted for processes across departments, from talent and hiring to development and security. These can be fine-grained and conditional, based on attributes rather than relying on static, rigid policies for granting or revoking privileges. Actions can be completed in seconds, to support JIT processes, while also creating a clear and auditable trail. This supports governance when it comes to showing that policies for passwords meet regulatory requirements.

With the measures above in place, hybrid AD automation helps to secure the attack surface between multiple AD domains and Entra ID tenants. However, what happens when those silos aren’t cultural or behavioral, and instead are more structural in the form of on-premises vs. Cloud infrastructures? Rather than switching screens for each tenant, IT leaders can now harness single-pane security and management.

Active Roles: Streamlined Microsoft directory security and management from a single console

Active Roles integrates seamlessly into an existing Microsoft directory environment, even simulating the look and feel to ensure smooth transition with a minimal learning curve. Active Roles allows organizations to consolidate all AD domains and Entra ID and Microsoft 365 tenants onto a single console, dramatically simplifying administration of the Microsoft directory environment and helping to ensure every identity account only has access to what it should.

In addition, fine-grained delegation helps to ensure every identity account has the proper privileges. Through hybrid AD automation, security and policy are enforced and synchronized across the Microsoft identity environment for real-time protection without delays.

Provisioning and deprovisioning can be performed with automated workflows, adding a layer of security while optimizing network bandwidth and licensing costs. Inactive accounts can be automatically managed and deleted based on policies.

Whether your environment is on-premises or hybrid, change tracking ensures you have visibility into actions made to your Microsoft identity accounts and directories. From one screen, these become consolidated sources of insight while generating a trail of demonstrable compliance. Of course, this streamlined approach to identity security and management also means savings for governance teams who can invest more on strategic projects and spend less on manual maintenance and routine tasks.
