Locking down Reader DC 2018

Hi,

We've been using Reader XI and recently found out that it's going end of life so we're looking at having to make the move to Reader DC.  Part of the reason we've been holding off is because we're avoiding the feature set that allows the user to 1) sign to the app using an Adobe ID 2) tie into other services like Box, Dropbox, etc.  We're mostly a Mac shop so I've been using the config guides:

Preference Reference for Acrobat and Adobe Reader

Feature lockdown — Customization Wizard DC for Mac

Preference Basics — Enterprise Administration Guide https://www.adobe.com/devnet-docs/acrobatetk/tools/Wizard/MacWizDC/lockdown.html

(I'll circle back to Windows once I sort out the Mac issue)

None of them seem to completely get me where I need to.  I've created this plist:

!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>DC (or 2015|2017|2018)</key>
  <dict>
    <key>FeatureLockdown</key>
      <dict>
       <key>bToggleAdobeDocumentServices</key>
       <false/>
       <key>bDisableSharePointFeatures</key>
       <false/>
       <key>bTogglePrefsSync</key>
       <false/>
      </dict>
  </dict>
</dict>

I've tried using the Adobe Acrobat Customization Wizard DC, however, every time I try to build I'm getting an error that the installer package invalid.  I've seen reports that Reader is not supported even though other Adobe articles (and reps) state otherwise.

I've tried manually moving the plist into place manually to /Library/Preferences (including making sure the owner and the permissions are set correctly), however, the app isn't recognizing the file is in place and all of those features still work.  I'm also seeing that if I run:

sudo defaults read /Library/Preferences/com.adobe.Acrobat.Reader.plist

then the file gets wiped from the machine after getting the error message:

2017-11-20 11:14:44.974 defaults[31124:3572384] Domain /Library/Preferences/com.adobe.Acrobat.Reader.plist does not exist

Any help and suggestions to get this to work would be greatly appreciated!!

Thanks!

Chris
