How can I access the AF Portal, OWA email, and other military sites using a CAC reader on a Samsung Galaxy Tab S4?

I downloaded the certificate and DoD certificates and still nothing. I’m not sure if I need a app to install on the tablet to open those certs. I’m also using a USB hub to USB C connection to tablet and tried both CAC readers. Maybe it could be cables, certs not opening to recognize readers as well. I’ll keep at it.

If you are successful, the middleware for your CAC reader is free, if you are unsuccessful, you end up with a Samsung brick.
