We have a bug with internet explorer 11 (version 11.0.9600.16438 - 11.0.1 (KB2888505)) when authenticate on https://www.e-legalite.com (one of our web sites) using certificate authentication. Indeed, once certificate selected in the dialog box, client can't log and after verification our server doesn't received certificate information, it appears that there is problem during the https negotiation. If we disable "Use TLS 1.2" at tools / internet /advanced options, the problem disappears. At the moment, we have that problem with internet explorer 11 and 10. On chrome, firefox, it works well and the connection used is TLS v1.2. Our server is Ubuntu 12.04 LTS Precise Pangolin which is up to date and is running Apache2.
Thanks in advance.
