The following terms are used in this section:
When it comes to Kerberos environments, clients and servers both act as Kerberos clients to the Kerberos server. The Kerberos server hosts a database to store the secret keys of its Kerberos clients. For a user, the secret key is the password of the user. For a host, the secret key is a random string generated and stored by the Kerberos server. The client stores the secret key in a keytab file.
The Kerberos server, also known as Key Distribution Center (KDC), contains two services:
There are three phases when a client authenticates to a service using Kerberos. A simplified process is described as follows. See RFC4120 for details about Kerberos authentication.
