As an organization adds applications and services, centralizing authentication and password services can increase security and decrease administrative and developer headaches. However, consolidating any service on a single server creates reliability concerns. High availability is especially critical for enterprise authentication services, because in many cases the entire enterprise comes to a stop when authentication stops working.

This article describes one method of creating a reliable authentication server cluster. We use an LDAP (Lightweight Directory Access Protocol) server to provide authentication services that can be subscribed to by various applications. To provide a highly available LDAP server, we use the heartbeat package from the Linux-HA initiative (www.linux-ha.org).
