How to configure Microsoft Entra Pass-Through Authentication Services
Microsoft offers the ability to enable Microsoft Entra Pass-Through Authentication for a Hybrid Environment Deployment.
The feature allows the user to have a seamless and faster log in experience to their Microsoft Office 365 account and services and allows users to sign in to both on-premises and cloud-based applications by using the same passwords. Pass-through Authentication signs users in by validating their passwords directly against on-premises Active Directory.
With Microsoft Entra Connect the Password Hash Synchronization and Password Write Back take a longer time to be replicated to the on the On-Premises Server (which can actually be on the cloud but referred to as On-Premises), and sometimes this process could take several minutes or required a manual update on the server using the command:
Start-ADSyncSyncCycle -PolicyType delta
*** It is highly recommended that you install the lightweight agent on more than 1 servers for a high-availability environment. ***
Below is the link to enable such configuration on your server.
