I don't know why they dissapear when you change to "Hide from camera" mode?
If you render the layer with shadow, not using render passes, the shadow is there.

I asked this question on support section but there was no response.

"Hide from camera" makes geometry transparent and traces through it as if it doesn't exit. Since we trace through it, we can't calculate any shadows, which would require Octane to not trace through, but stop tracing at that surface. At the moment you can't have both.

What are you trying to do?

Well, I'd like to have Layer shadow pass without cutout shape of an object that is casting the shadow like in the example below:

I know "Only side effects" mode would allow that but the shadowcasting object is not rendering so you have to render it twice, once to have a rendered object, second time the the layer shadow pass.

That is unfortunately not possible without having to render twice for the same reason I have mentioned above: If a ray hits an active object we can either bounce off that object to calculate its lighting and shading etc. or trace through and "look" what is behind. We can't do both at the same time. If you choose the "normal" mode, we bounce off obviously cutting off the shadow captured by the inactive layer geometry. If you choose "only side effects", we trace through showing the complete shadow but not rendering the active layer geometry.
