Subject: KNB Password Reset
|
|
641
|
|
|
642
|
Somebody (hopefully you) requested that your KNB password be reset.
|
|
643
|
This is generally done when somebody forgets their password. Your
|
|
644
|
password can be changed by visiting the following URL:
|
|
645
|
|
|
646
|
$cgiUrl?stage=changepass&cfg=$cfg
|
|
647
|
|
|
648
|
Username: $username
|
|
649
|
Organization: $org
|
|
650
|
New Password: $newPass
|
|
651
|
|
|
652
|
Thanks,
