looks like there is an error, in Kerberos the Client does not send the password to AS

00:04 Kerberos is a single sign-on network authentication protocol
00:22 Kerberos contains three essential components
00:39 Kerberos facilitates secure authentication process.
00:57 Client's password sent to authentication server
01:13 Authentication server sends the client a TGT
01:31 Client requests ticket from Key Distribution Center (KDC)
01:44 Client forwards key to file server
02:03 Kerberos provides time-limited access to file server

is the kerberos server in another machine?

different key = the next object secret key

Wow well understood ❤lots of love from India❤

wrong thing. Server or service has never connected to KDC because KDC knows both of keys of client and server. So TGS server sends encrypted Ticket (not Token) by Server key to client. Then client connects to Server. The Server decrypts TGS by key from keytab then both create established GSS context that lives 8 hours.

0:53 password is never shared on network in Kerberos

[egasimov]

For the first time, client sends data {username(userId) in plain text && password encrypted with his hashed(password)}
In Kerberos system, Authentication server verifies the client by trying do decrypt the encrypted text - user's password, with the key - hashed password (corresponds to userId in database).
Does it enough for Kerberos to be able to decrypt the cipher text successfully and allows Authentication Server fully verify client ?

How to be sure that decrypted text is actuall password of user ? One solution might come to mind is just by recomputing its hash and comparing them.
Could you, please clarify ?

The user doesn't send password to server in Kerberos.
