How to export PDF when embedded images have password protection?

[TomHolmes_G&I]

I've created an Indesign file which includes image boxes containing linked images. These linked images are old PDF files of client artwork proofs which I have previously applied password protection to. It asks for the password when I place them, which I type in and then they show up fine.

However, when I export the document as a PDF, it blocks the images and just shows them as grey boxes. I can't find any option or checkbox to override this. Can it be done, or am I going to have to create duplicates of every single linked PDF without password protection?

You need to remove that security in Acrobat.
