Hi all I'm trying to make a CSR for a server using certreq.exe and the subject DN has a comma in it. I have tried "\," , "\2C" and "%2C" in the subject filed of the policy.inf file that I use for making the CSR but whatever I use is exactly showed on the certificate. (It is not treated as a special character) Also I have the same problem with CAs. When I want to install Certification Authority on Win 2008 R2 and server's DN has a comma, the installation stops and shows an error message about "Invalid DN". How can I solve these problems?

thanks a lot. it worked for certreq.exe Is there a workaround for Microsoft CA naming too?

no, there are no workarounds.My weblog: http://en-us.sysadmins.lv PowerShell PKI Module: http://pspki.codeplex.com Windows PKI reference: on TechNet wiki
