Presto supports TLS-based authentication with X509 certificates via a custom certificate authenticator that extracts the principal from a client certificate.
CertificateAuthenticatorFactory is responsible for creating a
CertificateAuthenticator instance. It also defines the name of this
authenticator which is used by the administrator in a Presto configuration.
CertificateAuthenticator contains a single method,
which authenticates the client certificate and returns a
Principal, which is then
authorized by the System Access Control.
The implementation of
CertificateAuthenticatorFactory must be wrapped
as a plugin and installed on the Presto cluster.
After a plugin that implements
CertificateAuthenticatorFactory has been
installed on the coordinator, it is configured using an
etc/certificate-authenticator.properties file. All of the
properties other than
certificate-authenticator.name are specific to the
certificate-authenticator.name property is used by Presto to find a
CertificateAuthenticatorFactory based on the name returned by
CertificateAuthenticatorFactory.getName(). The remaining properties are
passed as a map to
Example configuration file:
certificate-authenticator.name=custom custom-property1=custom-value1 custom-property2=custom-value2
Additionally, the coordinator must be configured to use certificate authentication and have HTTPS enabled (or HTTPS forwarding enabled).
