X.509 certificate
A third party can provide one or more X.509 certificates that can be used for authenticating a user. When stored on secure devices, X.509 certificates combine a secure setup with ease of use for the user (no user ID or password needed).
Upon connection, the client provides a selected certificate, and optionally a selected extension, which is used to authenticate the user ID with your security product.
Note: This authentication method requires that encrypted communication must be enabled or
the RSED is on AT-TLS mode.
