Adobe Acrobat Plugin documentation

Hi guys

I already posted this on yammer but thought I might give this forum a shot as well 😉

Today I learned that the "native integration" in Adobe Acrobat reader for protected PDFs only works using a separate plug-in. Now, that's not that much of an issue by itself. But I can't find any documentation regarding that plugin in order to make it seamless for the end-user. Scattered across the www and yammer I found a registry key that makes labels more visible in Acrobat reader:

"Computer\HKEY_CURRENT_USER\Software\Adobe\Acrobat Reader\DC\MicrosoftAIP\bShowDMB"

Other than that there seems to be no documentation whatsoever.

Can anyone point me to any documentation?

Furthermore I'm having a couple of issues:

Is there a way to use SSO for the plugin in Acrobat reader or does the user really have to explicitly provide their e-mail address? I don't like this user experience as end-user training usually includes a recommendation not to provide their credentials at every random opportunity.

Protected PDFs opened in Acrobat do not offer the same screenshot / screen share blocking features as the integrated AIP Viewer does, is that on the roadmap?

Exporting a document to a PDF removes all protection and labeling (though it retains visual markings), and shows a warning message about it, printing to PDF does the same but without a warning (needs to be restricted anyway). Are there any plans to retain labels and protection when exporting?

Thank you guys
