Can we use "/" and "=" in CN and DN ?

[CALinux]

Hi everyone,   we are using OpenCA and OpenSSL. We want to create a certificate with special CN and DN  such as   CN=<surname>/<name>/<fiscal code>   DN="C="<surname>"/N="<name>"D="<birth date>   but OpenSSL don't accept this character, in fact when we put =/ it believe that is a second field with different value.   There is same special escape character? Where can we found something about this?   Thank you.   CALinux Staff.
