Error Messages
Error Message The saved user name and password entered for this profile are no longer
valid and have failed the LEAP authentication process. Please enter a new user
name and password. Remember to change them permanently in the profile using the
ACU Profile Manager.
Explanation
The username and password for your current profile, which uses saved credentials, have
expired or are no longer valid; therefore, your client adapter is unable to LEAP authenticate.
Recommended Action When the LEAP login screen appears, enter your new username and password
and click OK. The client adapter should authenticate using your new credentials. Then edit the
profile in ACU by changing the username and password on the LEAP Settings screen and save your
changes.
Error Message To run LEAP successfully, you will have to apply Microsoft Q241052
Update for the language version of your operating system as documented on
http://support.microsoft.com/support/kb/articles/Q247/8/05.asp. Please contact
Microsoft Product Support Services to obtain the fix.
Explanation
When the LEAP security module is selected during installation on a Windows 98 or 98
SE device, a Microsoft hot fix is also installed to fix two problems related to the use of LEAP.
However, only the English version of the hot fix is installed. Foreign language versions of these
operating systems require a hot fix specific to those languages.
Recommended Action Contact Microsoft Product Support Services to obtain the hot fix for languages
other than English. Without the hot fix installed, you may be prompted to enter your credentials at
the Windows login prompt twice. To work around this problem, enter your login credentials again.
Error Message Unable to LEAP authenticate. Please make sure you have entered the
correct user name and password and try again.
Explanation LEAP authentication failed.
Recommended Action Perform one of the following:
– Re-enter the LEAP username and password or cancel the LEAP authentication.
– To start another LEAP authentication process, select Reauthenticate from ACM or the
Commands drop-down menu in ACU, log off and log in again, or select Manual LEAP Login
from the Commands drop-down menu in ACU.
Error Message Unable to LEAP authenticate in the specified amount of time. The
network infrastructure might be down. You may also want to increase the LEAP
timeout value for this profile.
Explanation
The client adapter was unable to LEAP authenticate within the amount of time specified
by the LEAP authentication timeout value.
Recommended Action Increase the LEAP authentication timeout value on the LEAP Settings screen.
Then re-enter the LEAP username and password.
