Creating a domain and internal user management with LADP

Hello all,
I am new to linux and to network management but I will try to explain what I want to do as best as possible.

I have a computer cluster with a headnode and 14 nodes. I managed to create an internal LAN, with a DNS server on the headnode and a shared NFS folder. I now want to have a global user management system, so I won't need to create the same user on all nodes, but rather have a server (headnode) managing users.

I read about LDAP and installed it and configured it acording to manuals and everything seemed nice until I tried to connect to a user I created on LDAP from one of the nodes (i was able to do so from headnode where LDAP server is installed). I was sure that when LDAP required a domain name it was for LDAP to create that domain that it will manage the users in but I think that what my problem is that my nodes are trying to access my headnode to get the user information through a domain that doesn't exist.

I now think I completely missunderstood and that I need to first create a domain and only then install and configure LDAP.

My question is: Does LDAP configure a domain for me? Do I need to have the domain ready before I configure LDAP? If so how do I create a domain and add the nodes to it?

I hope I was clear enough to understand, please tell me if anything needs clarification.
Thanks in advance for any help available.

Domain name is pre condition. You have to create domain at first.

Steps for adding users:
1. Create Linux user
2. Create Linux user's ldap passwd file
3. Convert passwd.file to ldif file
4. Add ldap file to LDAP Directory using ldapadd

Thanks nini!
I feel so dumb, I was doing this with my friend and he was responsible for the DNS. I didn't realize that he created our domain name when he created the DNS and chose a Zone Name.. I now use the same zone name as my domain name in LDAP and all works (I think)!
At least I hope that maybe my dumbness might help someone else that might find this question helpful

I couldn't find the "makr this thread as solved" button under "thread tools". Sorry, but if there is an admin that can do that, and also explain to me where I might be missing the button, please do it for me if possible.
