Chapter 6 Using EAP Authentication

Overview

This chapter explains the sequence of events that occurs as soon as you or ACU’s auto profile selection

feature selects a profile that uses EAP authentication as well as after you eject and reinsert the client

adapter, reboot the computer, log on while this profile is selected, or are informed that your username

and password have expired. The chapter contains seven sections based on the profile’s authentication

type and its username and password settings:

• LEAP with the Windows username and password, page 6-3

• LEAP with an automatically prompted login, page 6-6

• LEAP with a manually prompted login, page 6-9

• LEAP with a saved username and password, page 6-13

• EAP-TLS, page 6-15

• PEAP, page 6-16

• EAP-SIM, page 6-19

Also provided are an overview of LEAP (below) and instructions for restarting the authentication

process when necessary (page 6-21).

Follow the instructions for your profile’s authentication type and credential settings to successfully

authenticate.

Note If any error messages appear during authentication, refer to Chapter 10 for explanations and

recommended actions.
