You are using the Diffuse output of the material node here, which usually has the shadows "baked in", but if you enable a separate shadow pass they are not included in the Diffuse pass (Color pass still has them). I'm not entirely sure if this is intentional or a limitation of the Blender Internal renderer though.

@brecht: Could you confirm if this is actually a bug?

That's not intentional, enabling other render passes should never influence the Combined pass. So it's a bug yes.

@brecht: Confused ... do you mean the Diffuse pass? Because that's the pass containing shadows only if no shadow pass exists. The combined Color always has shadows afaict.

I meant the Combined pass as you see in the image editor after rendering, that shouldn't be influenced by toggling the shadow pass on/off. As a consequence of that the Diffuse output in the material node should also be the same and always include the shadow, which it is not doing now.
