Chapter 6 Using EAP Authentication
Overview
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 eight sections based on the profile’s authentication type
and its username and password settings: LEAP (with the Windows username and password, with an
automatically prompted login, with a manually prompted login, or with a saved username and password),
EAP-TLS, EAP-MD5, PEAP, and EAP-SIM.
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 9
for explanations and
recommended actions.
Using LEAP
When LEAP authentication begins, the “LEAP Authentication in progress” message appears. This
message provides information about the status of authentication.
Table 6-1
lists and explains the stages
of LEAP authentication.

Status Message
Explanation
Starting LEAP Authentication
The client adapter associates to an access point, and the LEAP
authentication process begins.
Checking Link Status
The client adapter is LEAP authenticated, and the network
connection is verified.
Renewing IP Address
If DHCP is enabled, the IP address is released and renewed.
Finding Domain Controller
If you are logging into a domain and the active profile
specifies that the domain name be included, an attempt is
made to find the domain controller to make sure subsequent
access to the domain is successful.
