For authentication based on X.509 certificates the certificate and the private key of the user has to be deployed onto the workstation. Create a directory called .auth-agent in the home folder of the user and copy the certificate and private key of the user in PEM format into this directory. Use the cert.pem and key.pem filenames, or create symlinks with these names pointing to the certificate and the key file. The Authentication Agent will automatically use the certificate found in this directory.
