Hello, We have found the problem. On newer versions of their browser, microsoft blocks the use of certificate based on the hash algorithm md5 with tls 1.2 protocol so the connections fail because the certificate is not presented to the server. So I tried to disable the tls1.2 on the server, but this feature is not yet implemented on ubuntu 12.04 LTS release. A bug has been done to this address: https://bugs.launchpad.net/ubuntu/+source/apache2/+bug/1200136. When do you think this could be done?
