Windows Active Directory Plugin

First I am new here and I know very little of WP but I m trying to learn.

I am working with my Devs helping them configure certain plugins to connect to our Windows Active Directory in order to update the field in AD called THumbnailphoto. The way it should work is if I upload a users picture on their profile in WP that image should be exported to the THumbnailphoto field in AD so the users image shows up in Lync/Outlook etc.

However we cannot figure out why when WP writes the image to this field the image is completely unreadable. I have a util called AD photo that is able to do just this but its a windows util. Has anyone come across trying to sync images from WP back to Windows AD??
