In this chapter, we introduced you to the concept of identity management and showed the use of the 389-ds, the enriched OpenLDAP server on CentOS. It is enriched with a simplified setup script and graphical tools; however, we also saw how we can use traditional OpenLDAP tools to create and search entries in a directory. We finished the chapter by allowing a second CentOS server to use the account database shared by 389-ds supplying us with a single logon across many systems.

In the next chapter, we will discuss the Nginx web server, the new kid on the block, but a refreshing alternative to Apache.
