G'day I am running IIS 4 on NT Server with Tomcat 3.2.2 I have IIS set up to receive SSL requests (not tomcat). This has proven successfull on my development box. Where i have been able to use the following code to get the serial number of the certificate sent with a SSL request. (String)request.getAttribute("CERT_SERIALNUMBER") However I am having problems on my production box using this code. The serial number seems to be truncated - only by 2 characters - however this is 2 characters too many. If this helps it is truncated to 46 characters. I cannot seem to find any configuration problems. Has anybody ran into this problem or have they got any idea how to fix this. I was hoping it was just a checkbox that says truncate CertificateSerialNumber to 46 characters but alas it isnt. (: Please help me! Thanks Sam
