Chapter 6 Using EAP Authentication
Using LEAP with a Saved Username and Password
The LEAP Authentication Status screen appears.
Step 5 If your client adapter authenticates, the screen shows that each stage was successful and then disappears.
ACM now shows Authenticated, and the Server Based Authentication field on the ACU Status screen
shows LEAP Authenticated.
If the authentication attempt fails, an error message appears after the LEAP timeout period has expired.
Refer to the “LEAP Authentication Error Messages” section on page 10-18 for the necessary action to
take.
After Your LEAP Credentials Expire
If the LEAP credentials (username and password) for your current profile expire or become invalid,
follow the steps below to reauthenticate.
Step 1 Click OK when the following message appears: “The user name and password entered are no longer valid
and have failed the LEAP authentication process. Please enter a new user name and password.”
Step 2 When the LEAP login screen appears, enter your new username and password and click OK. The client
adapter should authenticate using your new credentials.
Note If you click Cancel rather than OK on the LEAP login screen, the following message appears:
“The profile will be disabled until you select the Reauthenticate option, Windows restarts, or the
card is ejected and reinserted. Are you sure?” If you click No, the LEAP login screen reappears
and allows you to enter your new credentials. If you click Yes, the current profile is disabled until
you select Reauthenticate from ACM or the Commands drop-down menu in ACU, reboot your
computer, or eject and reinsert the card. The Current Profile field on the ACU Status screen lists
the profile as being Disabled.
Using LEAP with a Saved Username and Password

username and password or you eject and reinsert the client adapter while this profile is selected, the
following events occur:
1. The LEAP Authentication Status screen appears.
2. If your client adapter authenticates, the screen shows that each stage was successful and then
disappears. ACM now shows Authenticated, and the Server Based Authentication field on the ACU
Status screen shows LEAP Authenticated.
If the authentication attempt fails, an error message appears after the LEAP timeout period has
expired. Refer to the “LEAP Authentication Error Messages” section on page 10-18 for the
necessary action to take.
