How to setup LDAP?

I’m a linux newbie getting thrown into the deep end and trying to setup an LDAP server. I have two computers running openSuse 11.2 that I’m trying it out on before setting up the thing for all the computers in the office. I used the software management tool in yast to search for “LDAP” and I installed the whole list, except for one package that caused a conflict. I did that for both computers. Then I tried to setup one as server and one as client, and thats about as far as I got. I’ve tried googling it, but I couldn’t find anything. Can someone give me directions, or a link to something? Thanks.

here it is: Chapter 4. LDAP—A Directory Service
and it’s better to upgrade to 11.4
