ticket granting server (Kerberos) (TGS)
Ticket Granting Server (TGS) is a component of Kerberos' Key Distribution Center( KDC) that generates and manages the session key.
The Ticket Granting Server maintains the session key that Kerberos uses to encode the Ticket Granting Ticket( TGT). The Kerberos Authentication Center issues service-approved tickets to users, which they can use to authenticate themselves in a domain.
