Which component in Active Directory performs authentication for Kerberos? Windows 2000 and later use Kerberos as its default authentication method. Kerberos is used by Active Directory Domain Services (i.e. Domain Controller) as the default authentication protocol when joining a client to a Windows domain.
4.What are the basic components of MS Kerberos, for example, Authentication Server, etc.? The KDC is comprised of three components: the Kerberos database, the authentication service (AS), and the ticket-granting service (TGS). The Kerberos database stores all the information about the principals and the realm they belong to, among other things.
Jul 16, 2018 · In infrastructure, there are different types of authentication protocols been used. Active Directory uses Kerberos version 5 as authentication protocol in order to provide authentication between server and client. Kerberos v5 became default authentication protocol for windows server from windows server 2003.
As the three-headed dog, Kerberos protocol has three main components. 1) A Client. 2) A Server. 3) A trusted authority to issue secret keys. This trusted authority is called as Key Distribution Center (KDC). Before we look in to Kerberos in detail, better to understand how typical key exchange works.
Kerberos protocol is built to protect authentication between server and client in an open network where other systems also connected. The main concept behind authentication is, two parties agreed on a password (secret) and both use it to identify and verify their authenticity.
1) Dave sends user name and his long-term key to KDC (Domain Controller). 2) KDC, checks user name and long-term key with its database and verify identity. Then its generates TGT (Ticket Granting Ticket). It includes copy of session key which KDC use to communicate with Dave. This is encrypted with KDC’s long-term key.
This is called as Ticket Granting Ticket (TGT). TGT contain two things, 1) Copy of session key that KDC use to communicate with Dave. This is encrypted with KDC’s long-term key. 2) Copy of session key that Dave can use to communicate with KDC. This is encrypted with Dave’s long-term key so only Dave can decrypt it.
