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.
M-Pin Strong Authentication System enables true two-factor authentication for Web sites and applications, based on the open source M-Pin Authentication Server and M-Pin Managed Service. The M-Pin Managed Service is a highly available, fault tolerant software as a service that issues cryptographic secrets to M-Pin Authentication Servers and Clients. The M-Pin Authentication Server uses just one leak-proof cryptographic key, and can't reveal any information about your users such as identity or login details, even if the key is compromised. The M-Pin Client is an HTML5 browser, so developers can easily integrate M-Pin into their Web sites and applications, enabling frictionless two-factor authentication and removing all username / password vulnerabilities.
