[GENERAL] certificate based authorization

[Sebastian - Anton PONOVESCU]

Hello
 
Is there a way to use certificate based authorization with postgresql? I
already implemented authentication, but among the people that my CA
certifies, and which I trust by the way, I want to distinguish to a
particular server who I grand access and who I don't even if they are
who they claim they are. And this based only on certificates not user /
pass or other mechanisms like LDAP / PAM.
 
Thank you and best regards,
Sebastian
