NFSManager
User Authentication panel 
¬
Use this panel to gain privileges to modify information in a domain.   

This panel appears if you're not logged in as root and you use NFSManager to change a NetInfo domain.

¬

¬

Type the root password for the domain here.
The root password of the domain is initially 
the same as the root password of the 
computer running the NetInfo server.

For security, the password doesn't appear as you type it.
