Request.getAttribute(“javax.servlet.request.X509Certificate”) Returns Null

问题

I have an issue with Request.getAttribute("javax.servlet.request.X509Certificate") returning NULL for some users during client certificate authentication and a valid certificate for others. For the users where this failed, if we delete and rebuild their Windows user profile, the problem get fixed. There is a workaround for this issue but I was hoping to avoid having our users rebuild their Windows account profile. Is there a specific setting in IE or ActivIdentity that might be causing IE to not sent the client certificate? We're using IE8 and ActivIdentity 6.1 on Windows 7 with Tomcat 6.

Thanks.

Your clients must configure ActivClient to make their certificates available to Windows. The Tools | Advanced | Make Certificates Available to Windows menu item will do this.
