Note that while this fixed it for me this is at best a work around and one that is only available to those that have a smartcard middleware installed on their machine that provides PKCS#11 libraries. This is a feature that has worked in Adobe for years without the need for these external libraries. Adobe please at least acknowledge that there is a problem and you are actively working on a real solution. ... View more

You are going to have to help yourself a little here since somebody can't walk up to your computer and fix it for you. Try google... "mac spotlight" "mac terminal" both bring up links that will help you understand what I'm talking about. Are you able to find the screen I included above? Send us a screen shot of it. google "mac screenshot" At some point did you install some software on your mac for your CAC card or did it use to just work with Reader? For general education on getting the CAC to work check out MilitaryCAC's Mac OS X support landing page ... View more

1) Open a Terminal (click spotlight and type terminal) in the terminal type: ls -lart path_to_your_lib That will list all the files in that directory and their permissions post that back if you are unsure. I actually don't think that the execute permissions are required (at least not with Centrify) Look at that other thread mentioned above for the paths it depends on what smart card middleware you are running. My posts have the path for where Centrify is installed (note I don't think the necessary libraries are included with Centrify Express) other posted for libCAC, I've never used that one so I don't personally know the paths. It may take some searching around you may want to watch a basic video on navigating a unix filesystem if you are not familiar with using a terminal and the cd and ls commands. 2) Open Adobe Acrobat Reader DC In the top menu (Where it says Acrobat Read) click preferences Select Signatures in the Preferences window Under Identities & Trusted Certificates click the MORE button. The PKCS#11... is in this window when you click it you get the option to "Attach Module" on the top. ... View more

Did try that and it did not fix my issue. ... View more

If you do the above and it doesn't fix it look at the Certificate details and make sure your validation path looks good. (For me it's good when there are no triangles and only one path found. If it shows any errors try updating the Adobe Approved Trust List (AATL) under Preferences -> Trust Manager. ... View more

We are using Centrify and PIV. I was able to fix two machines with Acrobat Reader DC doing the following... I didn’t need to mess with the permissions. So I don’t think executable permission are actually required thus the instratuctions are just… ·         In Adobe Reader DC, open Preferences, then go to Signatures --> Identities & Trusted Certificates --> More... ·         Cick "PKCS#11 Modules and Tokens" ·         Click "Attach Modules" o   Enter path to your PKCS#11 module; for Centrify this is /usr/local/share/centrifydc/lib/pkcs11/tokendPKCS11.so ·         Click "OK" ·         Click the little triangles to open up the module until you see the card ·         Click the card ·         Click on the email signing certificate (look for one that says Intended Usage: Digital Signature, Non-Repudiation) ·         Click the "Usage Options" popup menu and select "Use for Signing" ·         Click Close, then Click OK. ...

Come on Adobe - we're having the same problem with Acrobat Pro and PIV cards. Basically this is the only function justifying this product on my systems so while you may think this is a problem with a small feature from my perspective the entire application is broken. ... View more
