Custom security trimming SharePoint FAST Search results

I have created a custom search security trimmer for SharePoint Sea开发者_如何学编程rch. Unfortunately it doesn"t work with SharePoint FAST Search.

Is there any way by which similar custom security trimming of FAST Search results can be achieved ?

This issue is well known to Microsoft. My company has an open support request for it and other developers have noticed the same.

I'm not aware of any workaround. All we can do is wait.
