Need to enable the Enable Boot Manager authentication.
The KACE Boot Manager displays on a target device that has PXE booted from the appliance. Boot Manager authentication prevents users from manually selecting a KBE without authenticating with appropriate user credentials. By default, Boot Manager authentication is disabled.
1. On the left navigation pane, click Settings > Control Panel to display the Control Panel, then click General Settings to display the General Settings page.
2. Under PXE Options, select Enable Boot Manager Authentication and provide the Boot Manager username and password.
NOTE: The default Boot Manager password is admin.
3. Click Save.
The Boot Manager username and password are set for all PXE boot requests. Active sessions use the previous password if authentication was previously enabled.
