6.12.1 Connecting Using PAM Authentication

Java applications using Connector/J can connect to MySQL servers that use the pluggable authentication module (PAM) authentication scheme.

For PAM authentication to work, you must have the following:

A MySQL server that supports PAM authentication. See PAM Pluggable Authentication for more information. Connector/J implements the same cleartext authentication method as in Client-Side Cleartext Pluggable Authentication.
SSL capability, as explained in Section 6.9, “Connecting Securely Using SSL”. Because the PAM authentication scheme sends the original password to the server, the connection to the server must be encrypted.

PAM authentication support is enabled by default in Connector/J 8.0, so no extra configuration is needed.

To disable the PAM authentication feature, specify mysql_clear_password (the method) or com.mysql.cj.protocol.a.authentication.MysqlClearPasswordPlugin (the class name) in the comma-separated list of arguments for the disabledAuthenticationPlugins connection option. See Section 6.3, “Configuration Properties” for details about that connection option.
