I am trying to sigh a PDF document on my personal computer. The document requires a Common Access Card (CAC) digital certificate which I have.
Every time I try to sign an Adobe PDF I get the below error.
The CAC reader is installed and functional (confirmed by logging on to various DOD sites with my PIN).
How do i get Adobe Acrobat DC to recognize my certificates and sign the document?
I am using Adobe Acrobat DC version 2018.011.20040
Windows 10 Pro version 10.0.15063 build 15063
We apologize for the inconvenience caused, as per the description above, you are not able to sign a PDF file using the CAC digital certificate, Is that correct?
Using Adobe Reader, only PDFs with Reader Usage Rights enabled (through Acrobat software) can be signed using a digital ID.
Assuming you are using freeware Adobe Reader to sign the PDF file as I have checked the records with your current Adobe ID(email) and could not find any Acrobat license registered.
Try resetting Adobe Reader's Preferences once and reboot the machine, to reset the Preferences, please refer to the article How to reset Acrobat Preference settings to default.
Try disabling the Protected Mode once from Edit>Preferences>Security(Enhanced)>uncheck "Enable Protected mode at startup"
Note: Disabling the protected mode is only for testing purpose, please enable it back. Protected View feature for PDFs (Windows), Adobe Reader
If the issue persists, remove Adobe Reader using Acrobat cleaner tool Download Adobe Reader and Acrobat Cleaner Tool - Adobe Labs
Reboot the machine and install the latest Adobe Reader from Adobe - Adobe Acrobat Reader DC Distribution

You have to create a new digital ID.
