[syslinux] Password protecting menu entries using simple menu

[Baphomet]

Gents,

I've come across an issue using 4.0.5 -- not sure what I'm doing wrong
here, but I've tried a hundred different ways to password protect an entry
in one of my pxe menus, but every time I invoke the entry in the menu, it
prompts for the password (I've tried using MENU PASSWD xxxx and tried it
without, supplying a MASTER PASSWD and a blank MENU PASSWD after both a
BEGIN MENU and LABEL) and my entry kicks me back to the same menu without
executing the submenu. Strange thing is, if I remove the password,
everything works fine. I could swear this worked pre-4.x...

Any thoughts?
