Select Protocol Thresholds and Configuration > FTP. In Netscreen-Security Manager: In the device navigation tree select Security > IDP SM Settings, then select the Protocol Thresholds and Configuration tab. Under FTP, click the Show button. Set the Maximum Password length to the new value and click OK.
