LDAP Authentication Plugin for MySQL (auth_ldap) is an authentication plugin for MySQL Server. It allows you to create SQL users which are going to be authenticated using an LDAP server. This minimizes administrative duties, since your users will be able to reuse their existing accounts to access the database. The plugin requires MySQL 5.5.7 and up. It is compiled as an add-on, and does not require you to alter MySQL source code or recompile the entire server. The plugin adds support for LDAP using the openLDAP library.
