A client (a user, or a service such as NFS) begins a Kerberos session by requesting a ticket-granting ticket(TGT) from the Key Distribution Center (KDC). This request is often done automatically at login. A ticket-granting ticket is needed to obtain other tickets for specific services. Think of the ticket-granting ticket as similar

A typical operation with a KDC involves a request from a user to use some service. The KDC will use cryptographic techniques to authenticate requesting users as themselves. It will also check whether an individual user has the right to access the service requested. If the authenticated user meets all prescribed conditions, the KDC can issue a ticket permitting access. KDCs mostly operate with symmetric encryption.

The Kerberos server (KDC) receives the authentication request, validates the data, and replies with a TGT (Kerberos AS-REP). The most important point of this process is that the Kerberos TGT is encrypted and signed by the KRBTGT account. This means that anyone can create a valid Kerberos TGT if they have the KRBTGT password hash.

The KDC provides two core services: Authentication Service (AS) which authenticates clients and issues them tickets and the Ticket-Granting Service (TGS) which accepts authenticated clients and issues them tickets to access other resources.
A client requests a ticket for a service from the KDC by presenting it’s TGT and a ticket-granting service (TGS) request that includes the service principal name for the service it would like to access.
The KDC will use cryptographic techniques to authenticate requesting users as themselves. It will also check whether an individual user has the right to access the service requested. If the authenticated user meets all prescribed conditions, the KDC can issue a ticket permitting access.
What is KDC in active directory? The Kerberos Key Distribution Center (KDC) is a network service that supplies session tickets and temporary session keys to users and computers within an Active Directory domain. The KDC runs on each domain controller as part of Active Directory Domain Services (AD DS).
The Key Distribution Center (KDC) is implemented as a domain service. It uses the Active Directory as its account database and the Global Catalog for directing referrals to KDCs in other domains.
Key Distribution Center. The Key Distribution Center (KDC) is implemented as a domain service. It uses the Active Directory as its account database and the Global Catalog for directing referrals to KDCs in other domains. As in other implementations of the Kerberos protocol, the KDC is a single process that provides two services:
The KDC for a domain is located on a domain controller, as is the Active Directory for the domain. Both services are started automatically by the domain controller's Local Security Authority (LSA) and run as part of the LSA's process. Neither service can be stopped.
Neither service can be stopped. If the KDC is unavailable to network clients, then the Active Directory is also unavailable—and the domain controller is no longer controlling the domain. The system ensures availability of these and other domain services by allowing each domain to have several domain controllers, all peers.
