}Set up a netgroup named say "admin" under yp with your 
}administrators listed as a set of users, leave the domain 
}and machine fields empty (wild).
}In your server passwd files use +@admin instead of + to 
}include just the members of the admin group.
}
}The only problem I have found with this is that the yp master 
}passwd file is usually on a server...

Of course, if you're using YP, security has long gone out the window.....
