Hi,<br />I have imported a pkcs12 on my yubikey using yubico-piv-tool. yubico-piv-tool -a read-cert -s 9c returns the certificate ok. The purpose of it is to use this client certificate as a MFA challenge through a web based portal. I run this on Fedora 25. How do I make firefox see the yubikey as a personal certificate store?<br />thanks.<br /><br />update - After some googling I got this to work by installing opensc, and adding a security device pointing to /usr/lib64/opensc-pkcs11.so. After installing that package the yubikey 4's light is on continuously, and every second a kernel message is issued:<br /><br />Sep 17 12:58:28 marchost kernel: xhci_hcd 0000:00:14.0: WARN Event TRB for slot 7 ep 4 with no TDs queued?<br /> <br />what is causing this message?<br /><br />update2 - for the xhci_hcd messages see bug <!-- m --><a class="postlink" href="https://bugzilla.redhat.com/show_bug.cgi?id=959699">https://bugzilla.redhat.com/show_bug.cgi?id=959699</a><!-- m --> and more specifically pointing to YubiKey4: <!-- m --><a class="postlink" href="https://bugzilla.redhat.com/show_bug.cgi?id=1394501">https://bugzilla.redhat.com/show_bug.cgi?id=1394501</a><!-- m --><br /><br />Note that they only started spamming the messages log after having installed opensc.<p>Statistics: Posted by <a href="https://forum.yubico.com/memberlist.php?mode=viewprofile&amp;u=4900">Marc</a> — Sun Sep 17, 2017 10:19 am</p><hr />
