The library files include only the authentication_ldap_ XXX  authentication plugins. The client-side mysql_clear_password  plugin is built into the libmysqlclient  client library. 

Each server-side LDAP plugin works with a specific client-side plugin: 

•The server-side authentication_ldap_simple  plugin performs simple LDAP authentication. For connections by accounts that use this plugin, client programs use the client-side mysql_clear_password  plugin, which sends the password to the server as cleartext. No password hashing or encryption is used, so a secure connection between the MySQL client and server is recommended to prevent password exposure. 

•The server-side authentication_ldap_sasl  plugin performs SASL-based LDAP authentication. For connections by accounts that use this plugin, client programs use the client-side authentication_ldap_sasl_client  plugin. The client-side and server-side SASL LDAP plugins use SASL messages for secure transmission of credentials within the LDAP protocol, to avoid sending the cleartext password between the MySQL client and server.
