I'm going to guess you are talking about this, which after checking to be sure
does work okay for me:

global_settings
{
    ambient_light <1,1,1>
}

That's the default, and how to specify overall change to all ambient values in
texture finish statements whether or not 'ambient' keyword actually exists.
So this is essentially saying to multiply

finish {ambient 0.1}

by <1,1,1> (since rgb color is allowed). So using <1,0,0> will add a reddish
color to textures.

Won't work on ambient_light keyword as you wrote it. If this isn't the mistake
you have made I'm not sure how else you are trying to apply ambient light.

Also keep in mind that a radiosity {} used in global_settings will disable all
ambient settings. In such case keyword 'emission' will be required instead of
'ambient' in your finish statements.

Hope this was of help to you.
