[CentOS] which ldap do you like

To All,

I am going to try my hand at setting up an ldap server.  I have looked
at what is available and would like to ask your opinions as to what is a
good one to have.

openldap, centos-ds, and freeipa seem to be high on everyone's list.
Which one do you like, and does it have a good setup tutorial I could
use.  So far the tutorials I have looked at seem out of sync with the
curent versions of ldap servers.
