kerberos

Suppose I have four computers, Laptop, Server1, Server2, Kerberos server:

I log in using PuTTY or SSH from L to S1, giving my username / password
From S1 I then SSH to S2. No password is needed as Kerberos authenticates me

Describe all the important SSH and KRB5 protocol exchanges: "L sends username to S1", "K sends ... to S1" etc.
