Chapter 3 Configuring EAP Types

Configuring PEAP-GTC

Next Token mode for OTP is also supported. If the next token is needed, the backend server sends a text message (for example, “Enter Next PASSCODE:”) to indicate that the next token is needed. The PEAP-GTC module displays a prompt window that includes the text message sent from the server (see Figure 3-14). The user must get the next token from the OTP device or from the software and enter it in the prompt field.

Understanding PEAP-GTC Authentication

The PEAP-GTC module prompts the user for a username and password (or PIN for OTP) if the supplicant is configured to prompt for credentials during Windows logon or after the user is notified of an authentication error or failure.

If the user password expires, the PEAP-GTC modules prompts the user to enter a new password and to confirm the new password.

Finding the Version of the PEAP-GTC Module

The PEAP-GTC module version number, copyright information, and open-source software information are in About tab (see Figure 3-12).
