What happens if you configure the Azure AD tenant for a new subscription incorrectly?

Configuring the Azure AD tenant for a new subscription incorrectly can lead to access issues for roles because Azure AD controls user permissions and access rights across resources in your subscription. If the configuration is incorrect, users may not be assigned the necessary roles or may be assigned improper roles, leaving them unable to access required resources or services.

This situation can affect productivity and limit users' capability to perform their jobs effectively. Ensuring correct Azure AD configuration is crucial for establishing the right roles and permissions, which allows users to use their Azure resources as intended without encountering access restrictions.

Other considerations may arise, such as synchronization issues with on-premises Active Directory or security alerts triggered by unexpected behaviors, but the most immediate consequence of a misconfiguration tends to be related to role access.
