Examples with AuthenticationKerberosClient com.mysql.cj.protocol.a.authentication.AuthenticationKerberosClient used on opensource projects

Example 1 with AuthenticationKerberosClient

use of com.mysql.cj.protocol.a.authentication.AuthenticationKerberosClient in project aws-mysql-jdbc by awslabs.

the class NativeAuthenticationProvider method loadAuthenticationPlugins.

/**
 * Fill the authentication plugins map.
 *
 * Starts by filling the map with instances of the built-in authentication plugins. Then creates instances of plugins listed in the "authenticationPlugins"
 * connection property and adds them to the map too.
 *
 * The key for the map entry is got by {@link AuthenticationPlugin#getProtocolPluginName()} thus it is possible to replace built-in plugins with custom
 * implementations. To do it, the custom plugin should return one of the values "mysql_native_password", "mysql_clear_password", "sha256_password",
 * "caching_sha2_password", "mysql_old_password", "authentication_ldap_sasl_client" or "authentication_kerberos_client" from its own getProtocolPluginName()
 * method.
