Kerberos and SideCar are bundled together in the SideCar installer. SideCar is the utility that is always running on your computer, waiting for you to request a Kerberos ticket to authenticate your identity. When you need a Kerberos ticket, SideCar automatically prompts you for the information that Kerberos needs in order to connect. SideCar/Kerberos can be downloaded from the Web; see SideCar.
