I have a SCR3310 reader and I was using Centrify Express and my CAC to log into work on Friday. I did the same thing Saturday and it.

After upgrading to Sierra and I still had an older version of Express, it asked if I wanted to set up my system for CAC, CACNG, or PIV. If I chose PIV, will that screw up my system?

Can I change that choice? I've since updated the Express after following all of the clean uninstall instructions, but I was never asked again what the choice was for the system. I've notice a few strange behaviors, when asked to access my login keychain (to save a new password) if my card is in the reader, by username is greyed out and my password doesn't work. I pull the card out and it works. Also, in my login screen, believe it says pin instead of password if my card is in the reader. This makes be believe the system is set up for PIV. I'm not sure if this the problem, but I can't access many any CAC enabled DOD sites.

Unlike Adobe Acrobat Reader DC, which allows you to edit and erase certain parts of PDF files, Preview won't let you do it if it's only 1 page. I suggest getting a different PDF viewer, reader, and editor. Alternatives to adobe reader for mac.

I also noticed that I don't have a SystemCACertificates.keychain. I've associated my problems with this missing keychain, but now I'm wondering if I screwed up my system by selecting PIV. I saw another post question about the SystemCACertificates so if someone has a solution to that problem, look for that thread instead. Thanks for your help! Hi cresser1234, Welcome to Centrify. Could you help to clarify if the choice asked by Centrify Smart Card Assistant or other application? If possible, is there any screenshots could share with us so we could have a better picture for the issue?

Just performed the same step as yours, but did not see any prompt from Centrify Smart Card Assistant. Which version of Centrify Smart Card Assistant you have installed? Also, is it Express or Enterprise? Please feel free to contact us if you need any assistance.

Best Regards, Albert. Thanks for you response Albert, I think I had 5.1.7 installed at the time but I'm not sure. It would have been a few years old by now. I believe it was express, I know it was free so assuming express was the only free version in the past 2-3 years, that must have been it. I wish I could reproduce the prompt that I saw.

However, I had just opened Express a few days earlier (when I began noticing I couldn't sign pdfs back with OS X 10.11.?) so when it popped up after installing Sierra it looked familiar to me. That is why I believe it was Smart Card Assistant.app. I'm away from my backup disc until Tuesday afternoon or Wednesday morning. I will attempt to go back to the prior Express install using time machine unless you think that is a bad idea. If it helps, I ran the diagnostics with Express 5.3.3 the current version.

I can send that to you privately if that helps as well. Hi cresser1234, Thanks for your reply.

Much appriate for the diagnostics but I think there is no need for the 5.3.3 version as this is the version I tried on reproducing the issue too. I would suggest if you can do the upgrade on Centrify Assistant before plugging in the card(5.1.7 or 4.1.7 are really too old which may have unexpected behvaiours).

If you meet the issue after the upgrade, please take a screenshot and run the diagnostic then send it to me. Let me know if you met this again and I will give you my email. Please feel free to contact us if you need any assistance.

Best Regards, Albert.
