Error Messages

Error Message The EAP-FAST auto provisioning or PAC updating failed. The current profile is disabled until you correct the PAC configuration in the profile and reauthenticate.

Explanation PAC provisioning has failed. No PAC has been provisioned, and the profile is disabled.

Recommended Action Try again to authenticate using the existing profile. If automatic PAC provisioning is enabled, make sure to allow a PAC to be provisioned if prompted. If the authentication attempt fails again, modify the profile’s PAC configuration settings.

Error Message The entered password was incorrect. Please try again.

Explanation You incorrectly entered the PAC file password.

Recommended Action Carefully re-enter the PAC file password.

Error Message The imported PAC already exists on your local machine. Do you want to update it anyway?

Explanation You tried to import a PAC file with the same PAC ID as a previously imported PAC file.

Recommended Action Click Yes to replace the existing PAC with the new one from the imported file or click No to cancel the operation.

Error Message The new password must be different from the old password.

Explanation You entered your old EAP-FAST password in the New Password and/or Verify New Password fields on the Please Change Password window.

Recommended Action Enter your new EAP-FAST password in the New Password and/or Verify New Password fields on the Please Change Password window.

Error Message The Passphrase must be between 8 and 64 characters.

Explanation The WPA/WPA2 Passphrase that you entered on the Define WPA/WPA2 Pre-Shared Key window did not contain the correct number of characters.

Recommended Action Enter a WPA/WPA2 Passphrase with 8 to 63 ASCII text characters or 64 hexadecimal characters.

Error Message The password is empty. Please enter a password.

Explanation You chose the Use Saved User Name and Password option on the LEAP or EAP-FAST Settings window but did not enter a password, or you did not enter a password on the Enter Wireless Network Password window.

Recommended Action Enter your LEAP or EAP-FAST password in the Password field.
