EAP-FAST Error Messages and Prompts
Error Message Automatic PAC provisioning is enabled for this profile. However, a
valid PAC that matches the server to which the client adapter is connecting could
not be found. Do you wish to obtain a new security credential (PAC)?
Recommended Action Click Yes to provision a new PAC for this server using your existing credentials
or click No to cancel the operation. If you click No, the client adapter will fail the authentication.
Caution To prevent possible attacks from rogue access points, do not reprovision a PAC unless it is necessary.
Error Message While attempting to provision your PAC during auto-provisioning, the
network access device failed to authenticate itself. This condition might indicate
an attack on your password by a rogue access device. Try again with your current
password?
Recommended Action Click Yes to attempt to reauthenticate with your current password. Click No to
cancel the operation.
Note If the authentication attempt fails again, contact your system administrator to report a rogue access
device. Use strong passwords in the future to reduce the chance of your password being compromised;
see the “Creating Strong Passwords” section on page A-9 for tips on creating strong passwords.
