As part of increasing the security posture of Microsoft Entra Connect, Microsoft deployed a dedicated first-party application to enable the synchronization between Active Directory and Microsoft Entra ID. This new application will manifest as a first party service principal called the "Microsoft Entra AD Synchronization Service" (Application Id: `6bf85cfa-ac8a-4be5-b5de-425a0d0dc016`) and will be visible in the Enterprise Applications experience within the Microsoft Entra admin center. This application is critical for the continued operation of on-premises to Microsoft Entra ID synchronization functionality through Entra Connect.
