[newbie] strange bug on system login

[pete moss]

i noticed today that when i login through mingetty, when i give my
password, if i type extra letters after my password, then it still lets
me in.  is this supposed to happen?  for instance, if my pass is
'asdfqwer' and i type 'asdfqwertyuiop', then it still lets me in.  the
first part has to be the right password but after that it doesnt matter.

:P
