Plugin or File Plugin or File Name Server-side plugin name authentication_ldap_sasl Client-side plugin name authentication_ldap_sasl_client Library file names authentication_ldap_sasl.so , authentication_ldap_sasl_client.so Table 6.19 Plugin and Library Names for SASL-Based LDAP Authentication Authentication Plugins 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 following sections provide installation and usage information specific to LDAP pluggable authentication: •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. •Prerequisites for LDAP Pluggable Authentication •How LDAP Authentication of MySQL Users Works •Installing LDAP Pluggable Authentication •Uninstalling LDAP Pluggable Authentication •LDAP Pluggable Authentication and ldap.conf •Using LDAP Pluggable Authentication •Simple LDAP Authentication •SASL-Based LDAP Authentication •LDAP Authentication with Proxying •LDAP Authentication Group Preference and Mapping Specification •LDAP Authentication User DN Suffixes •LDAP Authentication Methods •The GSSAPI/Kerberos Authentication Method •LDAP Search Referral For general information about pluggable authentication in MySQL, see Section 6.2.17, “Pluggable Authentication” .
