MacOSX has kerberos built in, the GUI manager is in 
/System/Library/CoreServices/. The only hack to do is to create (touch 
is sufficient) a krb5.conf.

And last, *what* did you install and *where* it came from? Did you 
*just* install something or did you do something else? What did you do

What had happened? Could you log in? The description above doesn't make 
much sense to me.

It's not their business if you install something on the system that 
deeply changes your OS. Better if you called someone at MIT :)

Do you mean this? You restarted the non-working system holding down 
``T'' (was it? or ``F''? Anyway, the ``firewire drive'' mode). Then you 
saw the firewire logo floating on the screen and you could safely plug 
in the mac with a fw cable on another one. Nothing was shown on the

Something screwed your hd probably. Did you try the Disk Utility on a 
working mac while the other is connected in firewire mode? Did you try 
to look at the logs on the working drive (in /Applications/Utilities)?

Anyway, try those things.
