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!!!
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
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.
Anyone who want to explain or train or talk about IT better watch this video -- excellent explanation with a lot of 4W and 1H, and variation in the tempo.
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!
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.
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
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.

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.
Just to clarify all : When a user logged on, the Kerberos client on the user's workstation accepted the password from the user and converted it into an encryption key by passing the text through a one-way hash function. The resulting hash was the user's master key. The client used this master key to decrypt session keys received from KDC. So, the user password is hashed. The hash is used as the key. Now DC will also have the same hash of the user password. The DC will lookup the user, find it's hash, use it as the key and decrypt the authenticator file. Hence, symmetric encryption is used with hash of user password as the key. - Reference: msdn.microsoft.com/en-us/library/windows/desktop/aa380510(v=vs.85).aspx
Thanks for clearing the doubts.. I was confused with the password and shared secret key.. my last doubt is the shared secret key mentioned in Kerberos is nothing but the password which is in encrypted form? Am I right? Or both are different.
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.
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.
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!
the instructor Don should be keith's friend and one thing in common between them is that they have the key to teach what is required and clients are happy
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!
AWESOME VIDEO! VERY INSIGHTFUL AND EASY TO UNDERSTAND! I'm studying for CISSP. I previously had a knowledge of how it worked but not an understanding of what went on nor an in depth understanding of how the "what" went on. Your video is perfect. MAKE MORE FOR ALL DOMAINS IN CISSP! THANK YOU THANK YOU THANK YOU!
Medellin, this is Don Jones, a CBT Nuggets trainer. He has an IT expert with areas of expertise including Windows Server, PowerShell, SQL Server, and among a long list of others.
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..

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.
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!!!
Thanks for the comment. We are glad we could help out.
Is there a CBT Nuggets course on Kerberos?
This is the best explanation. Do not search for any other video.
Normally the best explanations are the simpliest ones. This video proves it. Thanks.
if every concept in computing and computer networking was taught as kerberos is explained here, we would all be experts in no time
Best kerberos ticket explanation. Thanks.
A note: You don't have to download 'kerbtray'. You can just type 'klist' and view cached tickets.
Have fun.
Awesome!! I I didn't know I had so many tickets on my system.
We are glad you enjoyed this MicroNugget Joe!

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
Fantastic. Gone from complete confusion to clarity in 7mins. Thank you
Excellent. No fluff; just solid information, presented engagingly.
Much appreciated!
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!
The way he explained is better than any other speaker i ever know...
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.
You really broke down a complex topic into a clear and concise way. THANK YOU!
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..
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
A great guy, Mr. Rob Z, brought me here. Thank you. Great video and explanation! Thank you Don Jones.
by far the best and simplest Explanation of Kerberos i have seen.
Explaining a Complex thing in Simple terms is an ART not SCIENCE......

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!
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.
a very clear & short explanation, thanks!
Fantastic explanation of Kerberos. Wish Don Jones was still doing IT training.
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!
