[Trisquel-users] Strange grub behaviour - Trisquel 7

[nux]

Grub has started asking for a username and password before it will boot other  
OS's in its menu. After some mooching about I found a reference in the  
grub.cfg file that seemed to refer to a name and password which subsequently  
turned out to be the ones I wanted.
Is this a new feature or a bug I should report?
