Password фuthenticator

Примечание

Ниже приведена оригинальная документация Trino. Скоро мы ее переведем на русский язык и дополним полезными примерами.

Trino supports authentication with a username and password via a custom password authenticator that validates the credentials and creates a principal.

Implementation

PasswordAuthenticatorFactory is responsible for creating a PasswordAuthenticator instance. It also defines the name of this authenticator which is used by the administrator in a Trino configuration.

PasswordAuthenticator contains a single method, createAuthenticatedPrincipal(), that validates the credential and returns a Principal, which is then authorized by the Контроль доступа.

The implementation of PasswordAuthenticatorFactory must be wrapped as a plugin and installed on the Trino cluster.

Configuration

After a plugin that implements PasswordAuthenticatorFactory has been installed on the coordinator, it is configured using an etc/password-authenticator.properties file. All of the properties other than password-authenticator.name are specific to the PasswordAuthenticatorFactory implementation.

The password-authenticator.name property is used by Trino to find a registered PasswordAuthenticatorFactory based on the name returned by PasswordAuthenticatorFactory.getName(). The remaining properties are passed as a map to PasswordAuthenticatorFactory.create().

Example configuration file:

password-authenticator.name=custom-access-control
custom-property1=custom-value1
custom-property2=custom-value2

Additionally, the coordinator must be configured to use password authentication and have HTTPS enabled (or HTTPS forwarding enabled).
