MicroNugget: How Kerberos Works in Windows Active Directory | CBT Nuggets

In this video, CBT Nuggets trainer Don Jones walks through how Kerberos works in Active Directory for Windows networks. Learn more about what Kerberos is and how it works with this MicroNugget video from CBT Nuggets.
Kerberos is the native authentication protocol in Active Directory. It's used by Windows networks everywhere. Understanding Active Directory’s more advanced concepts, like delegation, depends on understanding what’s happening under the hood in Kerberos.
Any time authentication is necessary, there are three players: the client making the request, the file server that contains the information, and the KDC or Key Distribution Controller.
In Kerberos, there’s no communication between the file server and the KDC. Because the client takes on the majority of the processing burden. That distributes the authentication workload across the network, securely.
First, the client constructs an authenticator, a package that establishes who the client claims to be, along with the date & time. These authenticators, and the tickets that will follow, have a limited lifespan.
Watch and see how the authenticator gets processed by the KDC, where the ticket-generating ticket (TGT) is stored on the client's machine, and how that TGT grants it access to various resources.
0:25: 3 different parties in authentication
1:25: What happens when a client attempts a secure log-in
3:10: A ticket-granting-ticket (TGT)
5:00: When a ticket is generated by the KDC
5:30: When a client sends a request to a file server
6:50: Overview

And the simplest.
This is the best explanation. Do not search for any other video.
Thank you Don and CBT Nuggets! This is definitely one of the best simple high level illustrations of kerberos! Those colored keys really did it for me!
Thank you for taking the time and effort to present this simple tutorial for everyone to understand how it works.
This is so much better than most of the other Kerberos clips out there. Thank you!
Thanks a lot for being so clear and pedagogic! It's the first time I heard about Kerberos and now I have a clear picture of what it looks like.
Straightforward concept explanation without having to delve on the technical portion. Great job!
Amazing, you explained an extremely complicated subject with brilliant clarity. Much, much appreciated.
Absolutely Brilliant Explanation of Kerberos! Thanks a lot Don & CBT! Keep up the Great Work!
You really broke down a complex topic into a clear and concise way. THANK YOU!
Excellent. Clearly spoken and presented in a visually descriptive way.
This video has been out for a while and I still think it does the best job of explaining kerberos authentication and what's in a ticket. I've used this to help explain the concept to my team many times. Thank you!
Fantastic. Gone from complete confusion to clarity in 7mins. Thank you
Awesome, thank you very much. I had to do the presentation for my final apprenticeship's work and had a part about Kerberos. I have read about this protocol, but with this video, I understood directly all I needed to know. Thanks a lot!
Thank you for taking the time to create such an awesome video. I finally understand Kerberos after all these years :P better late than never.
This is definitely the best explanation of Kerberos I have ever seen. Great job and Thank you.
I read about Kerberos many times but there were a lot of doubts. Your explanation with color lock and keys made it very simple for me. Thanks a ton!
Thank you! This was the clearest explanation of Kerberos. Helped me a ton.
I have seen lots of videos of kerberus, but this, as a matter of fact, help me to understand. great explanation.
There are several tutorials about Kerberos out there that make it seem extremely complicated; this has been done really well thank you!!
Normally the best explanations are the simpliest ones. This video proves it. Thanks.
Getting ready for my S+ I needed some visual explanation. Thank you for breaking down this so simple.
I must have watched half a dozen different videos over the last two days trying to wrap my head around Kerberos. Not a single other video mentioned the Kerberos Tray, or the CLI tool for the end user. This is BY FAR the BEST explanation I have found, bar none!! Fantastic job!!!
Short and sweet, nice! If only every video explaining IT concept in youtube is as neat as yours, it would be nice for every people of every age to learn IT
At last, a good video about Kerberos basics. Thanks.
Extremely informative, simple, lucid explanation. Many Thanks for this.
The BEST explanation by far... Love the colours used, makes it easier to understand!! Please upload more using this fantastic training method.
Very informative and the best explanation on kerberos I have seen. Thank you very much!
Thanx Don for all these explanation. I really love your MicroNuggets.
To the point, clear explanation. Best so far i have seen
I watched 5 or 6 vidoes and this by far is the best explanation....great job!!
WOW! I have spent hours trying to figure out how kerberos works and boom... 7 minutes later it all makes sense. Thank you so much!
Wow! So complicated topic explained so well, easy to understand.Thank You
Thank you so much! This is the first video I've found that made this concept clear to me.
A very nice overview of the whole Kerberos Process. Nice one !

This was very well done and explained in a simple way. Great work.
Thanks, this was really well done and easy to understand. I'm glad I watched this instead of the hour long video I was supposed to watch!!
this explanation about kerberos is perfect finally I could understand what's it and how it works. Thanks.
You have made an extremely complex subject easy ..whenever i attend an interview i watch it :)
After these two years, this video was very educative. I knew nothing about Kerberos and what the heck it was, now I know what it is and how useful it is.
Best explanation of Kerberos yet!
Thank you a lot! With this everything is way clearer to me than before ^^
This is by far the best and easiest to understand explanation of this that I have seen. If you ever make one explaining how SPN's and Kerberos delegation work I would be very grateful.
This is the easiest presentation of the lot. Thanks a bunch!
Excellent. No fluff; just solid information, presented engagingly.

Don Jones, Sir, you are awesome! Really cool way to explain the concept. Very easy to understand. :)
If you can't explain it simply, you don't understand it well enough. And you sir definitely understand it more than enough :) Thank you
the best way to explain how kerbero works. thank you so much.
Thank you for sharing your knowledge in a very simple but effective way.
Oh my god you blew my mind, that was the easiest explanation I've seen yet.
thank you for explaining the concept in such a simple matter. Your animation works too.
Man you put this in language that a moderately technical person can understand. Hours of meetings with folks trying to explain it in different ways and you nailed it in 7 minutes.
Thank you. This is the best video explaining on how Kerberos Work?
We are glad you enjoyed this MicroNugget Joe!
Thank you sir for explaining it in the simplest way possible.
In the last few days , I have seen multiple videos on the Kerberos step by step process.. This was the most simple and detailed one..
The best explanation I've ever seen! Thank you!
I'm trying to implement a Windows Authentication - Kerberos - Webcenter Content solution and, for starters, this gave me a clear explanation of what Kerberos does in between. Thank you!
讲的真好，清晰明了。 Crystal clear, Mr instructor.
A great guy, Mr. Rob Z, brought me here. Thank you. Great video and explanation! Thank you Don Jones.

Nice. When I read this in a book, it didn't make sense to me. I watch this video and it's so much clearer. Kerberos is such a cool concept actually. Thanks.
Thanks a lot! I am starting into AD and needed to better understand how Kerberos worked. This video was of tremendous help!
I had Kerberos in my university.. terrible explanations, I was completely lost. Now I went back on it and found your video. I now understand the main ideas way better. Thanks man

This is not exactly how this happens. Like the first request is always plain text from the client to the Authentication service of the KDC and subsequent communication between client and TGS.
by far the best and simplest Explanation of Kerberos i have seen. Explaining a Complex thing in Simple terms is an ART not SCIENCE......
This was spot on. Thanks for helping me to understand how Kerberos works :)
Excellent. Very simple explanation of a relatively complex topic.
Very simple and informative, thank you Don!
You covered this topic in a very easy way, thanks
I echo the sentiments of others in this thread. That was great!! Thank You
Thank you so much. That was indeed a great explanation of Kerberos. Cheers.
