Mac OS X Server for Xserve: How to Set Up Administrator Permissions
You can give specific users permission to administer servers using the sudo tool. Sudo is short for "Superuser do," a UNIX tool you can use to set up a list of users and the system commands that each is allowed to perform. If you use this tool, you don't have to reveal the root administrator password to all network administrators.
Read the sudo man pages to learn how to create a sudo configuration file.
Getting More Information
The Mac OS X Server Administrator's Guide, located on the Admin Tools CD as a PDF document, is your best resource for planning your network setup, configuring services, and administering services. It also includes recommendations for additional reading and study.

Help
Don't overlook another built-in resource in Mac OS X Server-the onscreen help. Choose Help from any Server Admin module, type your question, and get a list of search results that will help you complete your task. Most of the administration applications included in Mac OS X Server come with built-in onscreen help.
Despite your best intentions and careful planning, it is possible to create network settings that don't give you the results you expect or want. For example, if you inadvertently assign the same IP address to different servers, you'll see one server on the network, but not the other. Sometimes network settings can become corrupted and need to be set again.
