PEAPv0/EAP-MSCHAPv2 is the most common form of PEAP in use, and what is usually referred to as PEAP. The ensuing exchange of authentication information inside the tunnel to authenticate the client is then encrypted and user credentials are safe from eavesdropping. In most configurations, the keys for this encryption are transported using the server’s public key. It then creates an encrypted TLS tunnel between the client and the authentication server. PEAP is similar in design to EAP-TTLS, requiring only a server-side PKI certificate to create a secure TLS tunnel to protect user authentication, and uses server-side public key certificates to authenticate the server. The clients needs to trust that certificate, otherwise the user’s wont be able to connect to the wireless network. You can use here the default computer certificate from your internal PKI. Protected Extensible Authentication Protocol, Protected EAP, or simply PEAPĬlick on Configure to select a certificate to prove the identity of the RADIUS server to the clients. Protected Extensible Authentication Protocol (PEAP) In addition, each shared secret you use should be a random sequence of at least 22 characters that mixes uppercase and lowercase letters, numbers, and punctuation.įor authentication I will use the Protected EAP (PEAP) protocol.Įxtensible Authentication Protocol ( EAP) If you plan to configure APs by group in NPS, the shared secret must be the same for every member of the group. Use a unique RADIUS shared secret for each wireless AP unless you are planning to configure APs as RADIUS Clients in NPS by group. Here I need to add all my WLAN access points as RADIUS clients. Open the Network Policy Server console and select the RADIUS server for 802.1X Wireless or Wired Connections template to configure NPS by using the wizard.Ĭlick on Configure 802.1X to start the wizard. Now as the Network Policy and Access Services (NPAS) server role is installed you will have a new console named Network Policy Server. So first I will install the Network Policy and Access Services (NPAS) server role either on a domain controller or member server. NPAS replaces the Internet Authentication Service (IAS) from Windows Server 2003. Microsoft’s implementation of a Remote Authentication Dial-In User Service (RADIUS) server is for Windows Server operating systems later than Windows Server 2003 the Network Policy and Access Services (NPAS) server role. Set up the Network Policy and Access Services (NPAS) Server Role
