OpenSSO Integrates with EJBCA, Enterprise Class PKI Certificate Authority

There’s a couple of nice technical articles available that demonstrate how to integrate EJBCA and OpenSSO. EJBCA is an enterprise class PKI Certificate Authority built on J2EE technology. It is a robust, high performance, platform independent, flexible, and component based CA to be used stand-alone or integrated in other J2EE applications. EJBCA provides users with digital certificates for strong authentication and digital signatures. OpenSSO uses these credentials to provide single sign-on and authorization. Check out the articles.
