Kerberos is a network authentication protocol. It is
designed to provide strong authentication for client/server
applications by using secret-key cryptography. A free
implementation of this protocol is available from the
Massachusetts Institute of Technology. Kerberos is
available in many commercial products as well.
Version 5.0

Answer / gaurav dharasania
When you log in, your client contacts the Kerberos server
and uses your password to prove your identity. In return it
receives a special "ticket granting ticket" (TGT), valid
for several hours.
When your client wants to contact a network service on your
behalf (e.g. to mount a network file share), it first
contacts the Kerberos server with the TGT and the name of
the service. The Kerberos server issues a service ticket,
which your client presents to the actual network service.
The network service validates the ticket (without
contacting the Kerberos server) and allows the connection.

Answer / alchemist
After giving logon credentials an encryption key will be
generated which is used to encrypt the time stamp of the
client machine. User name and encrypted timestamp
information will be provided to domain controller for
authentication. Then Domain controller based on the
password information stored in AD for that user it decrypts
the encrypted time stamp information. If produces time
stamp matches to its time stamp. It will provide logon
session key and Ticket granting ticket to client in an
encryption format. Again client decrypts and if produced
time stamp information is matching then it will use logon
session key to logon to the domain. Ticket granting ticket
will be used to generate service granting ticket when
accessing network resources
