machine-User certificate on CentOS

[sciencedicas]

my environment used dot1.x authentication based on certificates, that means when a user plugs their windows machines, the machine send the computer-cert to be validated, if the machines in validated the the second phase would be user validation, in which the user presents the User-cert to the authentication server.
user can only be authenticated if he's presenting the cert after the machine authentication, meaning the user can only be on authorized machine,
that said.
I have now a couple CentOS machine that I would like to use on my domain, therefore I need to get the Computer-Cert plus the User-Cert.
the only documentation I see on how to get the certificates on Linux is to use with Web-Server, but I'm not running a Web-Server on those Linux Machines.

can someone assist me on how to get Computer-Cert and User-Cert on Linux, hot make sure the computer uses them on dot1x ?

thank you in advance.
