Intune compliance plays a crucial role in Conditional Access (CA) decisions, and misconfigurations can lead to user sign-in loops. In this article, we’ll discuss the root causes of such loops, along with solutions to help you quickly identify and resolve the issues.
Understanding Intune Compliance and Conditional Access
Intune compliance settings determine whether devices meet the required security standards for accessing corporate resources. These settings feed into CA decisions, ensuring that only compliant devices can gain access.
Common Loop Causes
- Device registration mismatches: Verify that the device is registered with both Intune and Azure AD.
- Browser and authentication broker considerations: Make sure Web Account Manager (WAM) is enabled in browsers for seamless access.
Excluding Emergency Access Accounts
Always maintain at least two break-glass accounts excluded from all CA policies to ensure emergency access when needed.
Using What If Tool
Simulate user sign-in using the Conditional Access What If tool in Entra admin center to identify which policy is blocking access.
Verifying Device Compliance
Ensure that the device shows as Hybrid Azure AD Joined or Azure AD Joined and is marked compliant in Intune.
Setting Policies to Report-only Mode
Set policies to Report-only mode when introducing new compliance grants, monitor for 1 to 2 weeks before enforcement.
