    Invalid policy constraint


      I'm trying to sign a PDF with my CAC (Common Access Card) but I see the error "the credential selected for signing is invalid". Digging deeper into the cert details, I see "invalid policy constraint".


      This used to work 3 weeks ago when I last successfully signed a PDF. All on the same platform:


      OS X 10.11.6

      Acrobat Pro 11.0.17


      Nothing obvious has changed on my end. I know my CAC cert is valid because I can sign the PDF with Reader on Windows 7.


      How can I sign PDFs again on my Mac?
