Simple shader question: let light affect all faces (remove occlusion?)

Hi all,

I am trying to learn the basics of shading and need help on the following issue:

Given a 3d object, is it possible to create a diffuse shader that doesn't occlude light?

With a normal light and 3d object, you have the following,

the dark face is away from the light.

What I need is instead that geometry doesn't occlude the light!

Sadly, with my current shader knowledge I don't even know what to start looking for, so please help!

Thanks.
