What is Kerberos?
Kerberos was written so that passwords wouldn’t have to keep going over the network where bad people could capture them
Kerberos does this by providing you with tickets which you get from a central Kerberos server at NCSA.
These tickets give you access to hosts and services (like email).
These tickets are sent encrypted over the network to so that even if someone managed to capture the packets, they couldn’t use them.
