Hola!

My system, debian wheezy amd-64, refuses to recognize my password. I am sure I am typing it correctly. 

I was able to , at login time, where grub pauses to ask which kernel tyo uise, 

to choose the maintenance option, dropping me to a shell. There I was able to type

sudo passwd kjetil

which asked to give a new password, which I repeated

then it said password succesfully changed. But no effect, 

I can still not login!

What is happeninmg?
