New Server Accounts and Home Directories

Greetings Everyone,

Hoping someone here has enough patience to help me figure out what I'm sure is a realtively simple problem...

I'm setting up a Mac Mini Server (10.6.8) in my Unviersity Lab and connecting 6 Mac Mini's (Snow Leopard). We have a bunch of people that need accounts, and obviously using a network account run from the server is the simplest and best option.

As I'm not THAT familiar with servers and/or Mac's, I've spent quite a bit of time looking through the Workgroup Manager and Server Preferences, and have managed to set up accounts for everyone and tweak them to my desired preferences.

However, when I try to login to a user network account from another computer, the login screen "shakes" and does not allow me to login. After some sleuthing through various forums, I've come to the conclusion that my "home Directories" are not set up properly.

This is where I am confused. I understand the idea behind the home directory, but do not know what to type in the dialog box in the following fields:

Mac OS X Server/Shar Point URL (afp?)

Path to Home Folder

Full Path

I plan to make the home directories on the Mac Mini Server's Secondary Hardrive under a folder called "Lab group".

Can anyone guide me to a tutorial or perhaps let me know what I should write in that field?

Also, if anyone has any great resources on setting up servers, that would be fantastic.

Many thanks (and apologies for such a silly question).

Cheers.
