System Admin Basics?

Hi,

I'm new to the world of system admin on linux machines and I'm having some trouble and was wondering if somebody could give me some guidance on where to look further. I've just about driven myself and co-workers insane the past few weeks.

The system I am working with currently consistes of a Duel AMD64bit CPU machine, 3 SUN Ultra Sparc machines, and 16 Dell Blades.

The 3 SUN machines are running Solaris 10. And the 16 Dell Blades are running LynxOS 4.0.

We are having a difficult time determining which OS to use for the 64bit machine. Originally the plan was to use Fedora Core 4. However, OpenLDAP was confusing the heck out of us and so we decided to try SuSe. From our understanding the SuSe ES contained a GUI for the LDAP configuration which would hopefully simplify the process. We are using SuSe 9.0.

The general idea of the system is to use the 3 Solaris 9.0 machines as a cross development environment for the LynxOS machines. The SuSe machine will be used as an analysis machine for system performance as well as the LDAP user authentication server, Subversion repository, and NFS server for the user directories and other data storage.

We currently have all of the OS's installed and running stand alone. The machines are also on a Cisco switch and are pinging each other. We also have the Sun machines NFS mounting file systems on the SuSe machine.

But we are now running in to major problems with LDAP and user authentication. Using YaST2 we configured the LDAP server (we thought O_o) and we were trying to use the Solaris 10 installation wizard to create the LDAP client profiles for the solaris machines. In the wizard it was saying that we had an error in Name Server. Unsure what that meant we asked around and all we learned was that we might need DNS server running on the SuSe machine as well.

Basically, I feel like we're in over our head and don't know how to get out.

Can anybody provide some basic guidance?

Do we setup DNS for LDAP? If so, how?
How do you configure LDAP on the solaris machine to talk with the SuSe machine for Authentication?
Would you recommend uprgrading SuSe 9.0? Or should we have stuck with FC 4?

thanx to anybody out there for any help you can provide
