push default open with program to server users

Hi All,

We have just upgraded to 10.9 server in an effort to speed up file operations to our Synology NAS.

Our users have to fill out some PDF forms and I need to force .pdf's to open with Adobe Reader.

Using profile manager, I have tried to push custom settings into the com.apple.LaunchServices.plist without any success.

I can log into everyones account and change it manually, however I'm sure this will be of value to the community.
