tutorial LDAP user authentication ?

[Rakotomandimby Mihamina]

Hi,
I have a Fedora Core 4 server and for the moment, users are
authenticated through the common /etc/passwd and /etc/shadow mechanism.

I would like to set up an openLDAP server to store and manage the users.

Would you have any good tutorial? all that I need is the Linux, pam  &
Fedora sides of the work.

I already play with LDAP servers for fun...
