Mastering Windows LAPS with Microsoft Entra ID & Intune: Native Cloud Architecture, Post-Auth Rotation & Incident Forensics

Local administrator accounts on Windows workstations represent one of the most critical attack vectors for lateral movement, credential dumping, and ransomware propagation. For over a decade, organizations relied on legacy Microsoft LAPS, which required schema extensions in on-premises Active Directory and an external MSI agent that failed on cloud-only workstations.

With native Windows LAPS built directly into Windows 10 and 11, Microsoft introduced a completely redesigned, cloud-native architecture natively integrated with Microsoft Entra ID and Microsoft Intune. This deep dive covers the end-to-end engineering blueprint: policy configuration, Post-Authentication Actions (PAA), RBAC access boundaries, and operational event log diagnostics.

Legacy LAPS vs Modern Cloud Windows LAPS

Configuring the Intune Cloud LAPS Policy

To deploy Windows LAPS in Microsoft Intune:

Post-Authentication Action (PAA): Eliminating Credential Residue

The single greatest architectural leap in modern Windows LAPS is Post-Authentication Actions (PAA). In traditional IT support, an engineer retrieves the local administrator password to install troubleshooting software. Once the technician walks away, that password remains active for the remainder of the 30-day rotation cycle—leaving a massive window of exposure for pass-the-hash attacks.

PowerShell LAPS Diagnostic & Event Forensics

When investigating LAPS policy compliance or key rotation on a workstation, examine the dedicated Windows Event Log channel at Microsoft-Windows-LAPS/Operational:

Granular RBAC Delegation in Microsoft Entra ID

Never assign Global Administrator or Intune Administrator simply to allow Tier-1 service desk technicians to view LAPS passwords. Microsoft Entra ID supports granular role delegation:
