Sorry; that was a typo.  I should have suggested:

   if exists user-class and option user-class = "iPXE" {
     filename "/ltsp/i386/menu-login.ipxe";
   } else {
     filename "/ltsp/i386/undionly.kpxe";

and have menu-login.ipxe contain

   chain -ar menu.ipxe

The idea here is that you don't use the presence of the 
username+password to decide to load menu.ipxe: instead your 
menu-login.ipxe script choose to load menu.ipxe (after prompting for the 
username and password).  There doesn't seem to be any need for you to 
make another DHCP request in this situation.
