What is the purpose of the Pre-Auth Check?
The purpose of the Pre-Auth Check is to authenticate users before the client sends the credentials to the Network Access Device (NAD). This ensures that the user credentials are validated via a RADIUS request to ClearPass before any further processing by the NAD occurs. This preliminary step can help in catching authentication errors early and providing a smoother experience for the user.
