Differences between TGT and Service Tickets

Hi Vilas,
A service ticket is a ticket you need to access a specific service. For
normal services, you get your ticket at the KDC and use it to access the
service.
But... Requesting that ticket is also accessing a service: the key
distributing service at the KDC. For that service, you also need a
ticket: the TGT. The name TGT in fact says it all: it's the ticket that
will grant you other tickets.
While acquiring the TGT, your password is checked by the AS. For service
tickets, only the content of your ticket is checked against the KDC by
the service, no further authentication from your side is necessary once
the AS has established your identity and granted you the TGT.
Kind regards,
Hans
