Follow the recomendation of Warp.

You should also check if you use ready made textures, mostly from some *.inc 
files. Some of those have some non-zero ambient values. The textures from 
metals.inc and golds.inc are big offenders.
It will be easy to spot after setting a default texture with ambient 0. Remove 
all lights and render. Any place that is still not black is using a texture with 
some ambient set to more than zero.
