Apple Mac OS X FAQ

On the login screen, the "Other" user is always appearing, but only on my PowerBook. I can't seem to locate the setting that disabled this feature as it was present under 10.1.x.
Assuming you're now running 10.2.x, check the NetInfo Manager (in Applications -> Utilities, by default) and make sure it is NOT set to "Enable Root User" login (under the "Security" menu).
