Part 1 of this series explores the current MIM landscape and options for moving to the cloud. In this second installment of our Transitioning Beyond MIM Revisited series, we explore governance as it relates to identity—specifically, Microsoft Entra’s rapidly evolving capabilities and their impact on organizations navigating the shift from MIM.
Identity governance ensures that the right people have the right access at the right time—and that organizations can prove it. A strong governance strategy should answer:
Operational efficiency is critical—governance controls must not hinder productivity or inflate audit costs.
Microsoft Entra ID Governance has introduced powerful advancements that can transform your approach to identity governance and accelerate the transition away from legacy solutions like MIM. Key capabilities include:
Let’s take a closer look at each one.
Microsoft Entra ID Governance delivers modern ILM features:
While some scenarios still require MIM, its role is shrinking as cloud-first identity management takes center stage.
Dynamic groups play a critical role in audits and control verification, making them a cornerstone of identity governance. Microsoft Entra ID Dynamic Groups work well in cloud-centric environments and now support on-premises Active Directory groups by designating Entra ID as the source of authority (SOA). This enables Entra ID Dynamic Groups to provision access to on-premises groups that were previously managed locally.
MIM still adds value by structuring identities and synchronizing on-premises AD accounts to Microsoft Entra ID via Entra Connect. It also provides attribute values that dynamic groups use to populate memberships, such as licensing groups, SaaS app access, and Azure role assignments.
Because governance for dynamic groups can be complex, recommendations follow a thorough analysis of business requirements. Options include retaining MIM, adopting Entra ID groups as the SOA, leveraging SCIM connectors, or implementing third-party ISV solutions. We expect Microsoft to introduce additional capabilities in this area over time.
Microsoft Entra ID continues to evolve rapidly, particularly in areas like access reviews and separation of duties (SoD). When combined with Azure Audit Logs, Microsoft Entra ID delivers the data organizations need for successful audits. This is a fast-moving space for Microsoft, with significant changes expected in both the near term (within six months) and long-term.
When necessary, both MIM and Entra ID SOA for groups can manage the creation and administration of on-premises AD groups. Now, access reviews can be implemented to ensure the right people maintain appropriate memberships—across both on-premises groups and Microsoft Entra ID.
On-premises synchronized Microsoft Entra ID accounts can enable users to request additional access to Azure Resources, such as licensing groups, SaaS applications, and Azure Role assignments. Entitlement Management manages the identity and access lifecycle by automating access request workflows, access assignments, reviews, and expiration.
Organizations have traditionally relied on MIM to manage external users by creating on-premises accounts for resource access. This approach lacks a definitive source of truth and often leaves accounts active indefinitely. Microsoft Entra ID Governance solves this challenge with robust controls, including:
Microsoft Entra ID Privileged Identity Management (PIM) reduces the risk of excessive or misused permissions by enabling time-based and approval-based role activation for sensitive resources. Currently, PIM is available only for Azure resources.
For organizations with on-premises privileged groups, Azure PIM can manage these groups using custom write-back scripts—an alternative to investing in the MIM PAM solution. Microsoft is expected to deliver more built-in Azure processes for managing on-premises groups in the future.
Azure PIM also supports guest user management by allowing administrators to:
This functionality can replace MIM’s traditional on-premises account solution for external users.
While MIM offers its own Privileged Access Management (PAM) solution for on-premises Active Directory, this approach is no longer recommended. Designed for isolated environments, MIM PAM is incompatible with modern applications and zero-trust frameworks.
Transitioning to a modern identity platform like Microsoft Entra Suite can be complex, and many organizations encounter roadblocks like brittle legacy workflows, disparate systems, complicated reserve value scenarios, and a lack of visibility that make migrations seem daunting. The good news: with a clear strategy and the right tools, modernization is absolutely achievable.

ILM is the process of creating, managing, and removing user identities and their access privileges to resources and applications throughout an organization’s environment. It encompasses onboarding new users, updating access as roles or attributes change, and deprovisioning accounts when users leave. A well-defined and streamlined ILM process is crucial for security and efficiency, as poor ILM can lead to productivity issues and security gaps by improperly managed accounts.
Dynamic groups are a key component of identity governance, automating membership based on user or device attributes (e.g., job title, department or location). When attributes change, such as a promotion or relocation, users are automatically added or removed from the appropriate dynamic groups.
This ensures users have the right access when needed and lose it promptly when roles change or employment ends.
Access reviews periodically verify and recertify user access to resources like groups, applications, and roles. They help maintain compliance and improve security by reducing excessive or outdated permissions.
Access reviews enable organizations to:
PIM minimizes the risk of excessive or misused permissions by enforcing least privilege principles. It provides time-based, approval-based, and just-in-time role activation for sensitive roles, eliminating permanent admin access.
