As David has said, you should read the Kerberos FAQ, or most definately you 
should read "Designing an Authentication System:
a Dialogue in Four Scenes". This is excellent reading. I only wish I could 
find more writings of this nature instead of the usual technical books.

The name Kerberos is used because it is the name of the three-headed watch 
dog in Greek mythology. Most people know of this dog as being called 
Cerberus, but this is actually the Roman (Latin) tranlation of the correct 
and original Greek name, Kerberos.
