Has anyone else encountered this problem? Apparently, Verisign has switched to new certificate scheme, as of a few months ago. Verisign's explanation is here: http://www.verisign.com/support/advisories/page_029264.html (yes, it's available as an https page as well, and if you go to that same page as https, the cert checks out.) Now, when I go to my work's remote login site using OS X https://securelogin.gov.ab.ca I get a certificate error (I get no error with Windows). I'm pretty technical, and I can't even figure out how to get a copy of this new Verisign certificate, signed with a key that I already do trust, to import it into my X509Anchors keychain... So my questions three: - Can someone else using a fully up-to-date OS X check whether they get this error? - Can someone else using a fully up-to-date OS other than Windows check for this error? - Has anyone encountered this same warning about the Verisign Class 3 Server Certificate elsewhere on the web? I see two possibilities - Verisign just didn't bother to get anyone but Microsoft to include their new certificates - they just don't care about the rest of the world. - If the site in question distributed a full certificate chain, then it could get back to something Macs trust, but they just haven't configured it to do so, because it was only tested from Windows.
