Unity 5 Surface Shader - Ambient issue

Hey everyone,

I am trying the new Unity 5 and it is really great but I am facing an issue when using Surface shader. As the issue is the same when using the Legacy Diffuse shader I'll talk about this issue using this shader.

If I apply the Legacy Diffuse shader, the material uses the ambient light defined in the Scene Render Settings. But if I turn my object static, it uses the Indirect lighting provided by the Global illumination...
