If this is really true then you have found a bug, but I assume that you made a 
typo and that you meant Db's instead of D's (or did you mean "natural sign" 
instead of "flat"?)

No, this is definitely not true - I know a lot of musicians - and we ALL agree 
that accidentals needs to be repeaten in new octaves.
Kurt Stone has more on 20th century common notation - and he also states this.

You don't state which Lily you use.
In 1.4.anything there's not much you can do. I don't think it's possible to 
turn off the auto-accidentals - and if you remove the accidental engraver 
completelhy I don't even think that explicit accidentals are typeset.
In 1.5.enough you can add
\property Score.autoAccidentals = #'((measure-any-octave . 0))
(Syntax about to change - as soon as I get time)
to the start of the music. measure-any-octave means that the accidentals are 
remembered for a number of measures and in all octaves. 0 means that 
they "survive" over 0 bar lines. That is: They die at the end of the measure.
If you wan't to turn off automatical accidentals (and place them yourself 
with ! and ?) then use
\property Score.autoAccidentals = \turnOff
