Issue Description
How Can I Perform Certificate Authentication and What Is the Difference Between Certificate-Anonymous Mode and Certificate-Challenge Mode?
Solution
Certificate authentication verifies the identities of SSL VPN users using a CA certificate in either of the following modes:
-
Certificate-anonymous mode: The SSL VPN gateway extracts user information carried in the CA certificate to verify the identities of SSL VPN users.
-
Certificate-challenge mode: The SSL VPN gateway verifies the identities of SSL VPN users by extracting user information carried in the CA certificate and meanwhile implementing local or server authentication.
