Here's a pretty extensive article on how LDAP authentication works, 
which will get you the proper entry format, but they don't mention the 
easiest way to set up the system to authenticate on RedHat based 
systems: use a neat program called authconfig. It's a type of graphical 
commandline interface to set up authentication. It makes the process 
very simple: click a checkbox, fill in a few textboxes, and you're set 
up and ready to go.

Hope this helps,
