Create a Layered Shader.

Connect a Surface Shader with a amb_occlusion in its Out Color, in Color of Layered Shader.

Connect the file with alpha channel in Transparency of Layered Shader.

Change the Compositing Flag to Layer Texture.

Make a test.

I think you need to be using the Cutout Opacity function in the mia_material_x. It appears you're putting your alpha texture file into the Transparency channel, not the Cutout Opacity channel.

There's no need to render a separate layer or pass if you're just trying to get the opacity correct.
