Limited access to server for modifying accounts?

Thanks for the response. Will that allow me access to the program on the server to change passwords for users and add/modify users? How would this work exactly? Do we enter that command line on the server or each individual machine?

Sorry, I am not familiar with servers. I know macs, but not the server stuff.

Thanks.

I think I forgot to mention the server is not in the classroom. I would be remote logging in via remote access (I think).

I think I found what I was looking for:

To add limited administrative capabilities:
1 In Workgroup Manager, click Accounts.
2 Select the user account you want to work with.
To select an account, click the globe icon above the accounts list, choose the directory
domain where the user’s account resides, and then select the user.
3 To authenticate, click the lock and enter the name and password of a directory
administrator.
4 In Privileges, choose Limited from the “Administration capabilities” pop-up menu.
5 To control the level of user or group administration, click the Add ➕ button and drag
users and groups from the drawer to the “User can administer” list.
6 Select a user or group from the “User can administer” list and then select the
administration capabilities you want the limited administrator to have.
To give administrative control to all users and groups, select “All Users and Groups” and
then select administrative capabilities.
7 Click Save.

Now I just need to be able to open the workgroup manager from a Mac in the classroom after he does the above, right?
