Windows 7 wired 802.1x EAP-TTLS authentication method RRS feed

  • Question

  • Hi, I have problem with changing authentication methods for 802.1x on network interface. Service "Wired Auto Config Service" is running but I cannot change authentication to EAP-TTLS (PAP). When I try to change authentication method I can chose only between two options - Microsoft: Card or certificate and Microsoft: PEAP

    I tried reinstall network driver (Intel network card) and change network card to Realtec, but no result. Please help me how to add EAP-TTLS method to Windows network driver.

    Thanks,

  • Hi PetroSeva,

    Please make sure if it supports EAP-TTLS, Windows will need additional software. PEAP with MS-CHAPv2 is built directly into Windows.

    EAP-TTLS is a standards-based EAP tunneling method that supports mutual authentication and provides a secure tunnel for client inclusion authentication by using EAP methods and other legacy protocols. The addition of EAP-TTLS in Windows Server 2012 provides only client-side support, for the purpose of supporting interoperation with the most commonly-deployed RADIUS servers that support EAP-TTLS. Please refer to the link below about TTLS configuration items.

    The EAP-TTLS method uses server-side certificates to set up authentication between clients and servers. The actually authentication is, however, performed using passwords.

    Hope it will be helpful to you
