RADIUS client: Converts requests from client application and sends them to RADIUS server that has the NPS extension installed. This gives your VPN the full breadth of Azure AD protection, including Conditional Access, Multi-Factor Authentication, device compliance, and Identity Protection.Ĭlient application (VPN client): Sends authentication request to the RADIUS client. Rather than relying on RADIUS and the Azure AD Multi-Factor Authentication NPS extension to apply Azure AD Multi-Factor Authentication to VPN workloads, we recommend that you upgrade your VPN’s to SAML and directly federate your VPN with Azure AD.

Any others that depend on the RADIUS protocol to authenticate users into the service.

You need to add Multi-Factor Authentication to applications like Once successful, the client application is allowed to connect to the service. The user then receives a challenge on their mobile authenticator. The Windows NPS server authenticates a user’s credentials against Active Directory, and then sends the Multi-Factor Authentication request to Azure. If a customer wants to apply Azure AD Multi-Factor Authentication to any of the previously mentioned RADIUS workloads, they can install the Azure AD Multi-Factor Authentication NPS extension on their Windows NPS server. Microsoft Windows Server has a role called the Network Policy Server (NPS), which can act as a RADIUS server and support RADIUS authentication.Īzure Active Directory (Azure AD) enables Multi-factor authentication with RADIUS-based systems. Many applications still rely on the RADIUS protocol to authenticate users. Remote Authentication Dial-In User Service (RADIUS) is a network protocol that secures a network by enabling centralized authentication and authorization of dial-in users.
