The credential selected for signing is invalid - Army CAC, Mac OS 10.14
Hello all.
I've recently encountered an issue where Adobe Acrobat Reader DC will not allow my military CAC credentials to digitally sign pdf forms. I wish I could pinpoint exactly when this started happening but I don't sign documents often enough to know. I DO know that I got an updated ID this last March, so that potentially has something to do with it. It's an Oberthur ID One 128 v5.5a D
I can see two of the card's four certificates when I "click to sign". I can select either, continue on, see what the signature will look like, click sign, enter the passcode, give the post-signed file a new name, but then when it actually goes to sign I get a pop-up "Error encountered while signing: The credential selected for signing is invalid". I click "ok" and the signature field goes blank.
I have done soooo much internet searching and have been unable to find any posts with the same situation. I've bought a new CAC reader to try and eliminate that - uninstalled and downloaded / reinstalled Adobe - restarted computer - reset my keychain login to default - cleared out my old / expired CAC certs - ensured my computer / Adobe "trusted" all of the certs always....
I just don't know what else to do. Help me oh mighty tech world!!
Thanks in advance!
