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

the best explanation of kerberos I have ever seen! Thank you.
I concur!!!
About to comment the same
@@nonsougwu8040 hear! hear!
yes. it is. same for me.
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!
This is so much better than most of the other Kerberos clips out there. Thank you!
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
You really broke down a complex topic into a clear and concise way. THANK YOU!
Straightforward concept explanation without having to delve on the technical portion. Great job!
There are several tutorials about Kerberos out there that make it seem extremely complicated; this has been done really well 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.
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 for taking the time and effort to present this simple tutorial for everyone to understand how it works.
Amazing, you explained an extremely complicated subject with brilliant clarity. Much, much appreciated.
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!
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!!!
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!
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
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.
that was amazing video .... ohhh my god! you don't know how much time I spent to learn the concept of Kerebros thanks
derka derka derka
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.
Normally the best explanations are the simpliest ones. This video proves it. Thanks.
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
Excellent. Clearly spoken and presented in a visually descriptive way.
This is definitely the best explanation of Kerberos I have ever seen. Great job and Thank you.
I have seen lots of videos of kerberus, but this, as a matter of fact, help me to understand. great explanation.
Absolutely Brilliant Explanation of Kerberos! Thanks a lot Don & CBT! Keep up the Great Work!
We are glad you enjoyed this MicroNugget Joe!
Thank you. I am not much into kerberos & was looking for some tutorials that can help me understand the same. Came across this video which helped me understanding kerberos funda's in a very simple way. Thank you once again.
rohit uppal You are welcome! Make sure to visit our channel again if you have any future questions. We have over 500 free tutorial videos available that may just help answer your question.
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.
Getting ready for my S+ I needed some visual explanation. Thank you for breaking down this so simple.
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.
At last, a good video about Kerberos basics. Thanks.
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!
Oh my god you blew my mind, that was the easiest explanation I've seen yet.
The BEST explanation by far... Love the colours used, makes it easier to understand!! Please upload more using this fantastic training method.
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.
Thank you! This was the clearest explanation of Kerberos. Helped me a ton.
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..
You have made an extremely complex subject easy ..whenever i attend an interview i watch it :)
A very nice overview of the whole Kerberos Process. Nice one !
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
Thank you a lot! With this everything is way clearer to me than before ^^
Thanks for the comment. We are glad we could help out.
Is there a CBT Nuggets course on Kerberos?
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.
Excellent. No fluff; just solid information, presented engagingly.
Much appreciated!
Thank you so much! This is the first video I've found that made this concept clear to me.
讲的真好，清晰明了。
Crystal clear, Mr instructor.
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.

Have fun.
Awesome!! I I didn't know I had so many tickets on my system.
This is much much clearer explanation. Thank you.
The only thing that explained properly in all the other videos I watched so far is that 'Three headed dog' crap..
