Azure AD App Registrations, Enterprise Apps and Service Principals

[@expat64]

This is by FAR the best explanation of what can be a very confusing topic that I have seen. You out did yourself here John, thank you!

[@NTFAQGuy]

Glad you enjoyed it!

[@CrustyBoot]

I completely agree!

[@clemiboi]

The designer for App Registration/Enterprise apps/service principals must have been so bad.... thanks for this video

[@oem73]

I second that motion. Excellent explanation. Thank you!

[@UnCatolico]

Agree by FAR also. Excellent. Congratulations and thank you so much for this quality training video.

[@helennamannila4464]

Congratulations - what has always been a really confusing area has now become crystal clear. I had to watch it twice to make sure I thoroughly understood it (and will probably have to watch it again if I need to remind myself a few months down the line). But you have achieved what the Microsoft doc could not. (Also had much-needed research into OAuth 2 in the process, so win-win!) Thank you :)

[@NTFAQGuy]

Glad it was helpful!

[@sachingoyal22]

Thanks so much. This video is now 3 years old, still explains the concepts like no other video does.

[@gdr1174]

When I first started to take an interest in technology it was through reading incredibly dry text books from the library. Thank god for people like John who make the constant learning journey much more accessible and enjoyable 👍

[@Tnub2]

Wow, great content, John! When you showed how the Enterprise Apps are only listing the Service Principals and that you would have one SP in every AD that wants to access the app - that was really an "AHA-moment" for me. Thank you so much for this excellent explanation

[@NTFAQGuy]

Glad it was helpful!

[@mromar2724]

This has to be the best explaintaion on workings of AAD I have ever seen. Thank you

[@NTFAQGuy]

Glad it was helpful! Thanks!

[@ernestmfakudze]

@mromar, I totally agree with you. Amazing explanation @John

[@maciejpakulski1182]

Totally agree. I've seen a few videos that tried to explain this topic, however John's video is really the best. Stellar work.

[@mhydeist3610]

I've recently passed the AZ-700 because of your videos. Thank for making them. Recently, I take interest in security and yet again your knowledge help my through a lot. How can I thank you enough!!!

[@NTFAQGuy]

Glad you like them and huge congratulations 🤙

[@emmiauranen]

I can't believe you made a video of this over three years ago! So glad you did, because now it's more understandable. BTW, your handwriting is so much better these days 😄

[@davidaranda2528]

Finally, someone who can explain this whole process in a way that actually makes sense. Great video, keep it up!

[@NTFAQGuy]

Thank you

[@jonathanku8599]

excellent explanation. I was setting up App Registrations in Terraform and couldn't' understand where the Enterprise Application was getting created from, but now your video explained it

[@kimicheng5611]

I was totally lost when I was watching this video for the first time. After I learned OAUTH2 and other concepts here and there for several days and come back to watch again, all the contents in this video are crystal clear and really well organized and presented. Thank you so much.

[@asmiles9057]

Woah! I read through so many different sites trying to understand these topics without any success. This video cleared up everything for me. Thank you for creating this.

[@michaelr1154]

After 3 years, i keep coming back to this video. Love your work as always John!

[@sgphillips101]

Brilliant training from John on a subject I have always had problems grasping. I watch alot of John's courses, he is an amazing teacher.

[@sabokunogaraa]

I'm really amazed. The Microsoft docs were making me run in circles but this video was more than enough to understand such a complex topic

[@KaezerMusik]

Holy shit John. I have been struggling with this topic and looking at all kinds of resources to grasp it. And you come along once again with such a bang on lecture. I dont know how you always end up being so successful at teaching me things others fail to upload in to my brain. Thank you!

[@NTFAQGuy]

Glad could help

[@stasizzle]

100% the best video on AAD app registrations, ent apps and SPs! I just watched several of them and NONE were as clear as John's.

[@sachindhamija3061]

I really search for all your videos over internet..You are one of the best trainer I have found...lucky to have you in youtube ...Thanks !!

[@NTFAQGuy]

I appreciate that! Thank you!

[@tarunacharya1337]

beautifully explained, my search for a a proper explanation of the App Registrations and SP's finally ended with this video. Thanks John

[@EA33964]

This is fantastic! I've been struggling to understand this, not sure why everyone else made it so complicated to understand, pretty sure some just want to flex their technical jargon to confuse people 😄 Thank you !!!

[@rolandovirjan780]

Half hour of explanation and pages of diagrams, "that's literally all there is to it!". Made me smile lol. Seriously though, great video and very helpful thank you.

[@ahmadabdalla90]

One of the most complicated topics in Azure AD. Well explained 👏🏼

[@NTFAQGuy]

Glad you think so! Thank you!

[@lysajane3643]

Wow! Absolutely brilliant. It doesn’t quite come through like this when reading the documentation over and over again. TY for explaining the Svc Principal and the difference between App Reg and Enterprise Apps.

[@titlibhakta6271]

My god! How can he explain everything so clearly and I discovered I knew wrong information till today after watching this video. Thank you so much ❤

[@michaelwaterman3553]

Right, so I was trying to get my head around the concept of Apps and enterprise apps, read a lot of blogs and the official documentation. Just didn't stick.... After watching this it all makes sense! Thanks John!

[@Brianle180]

That is the best explanation I have found so far. Your contents are very quality, thanks John!

[@rafaelnegron5662]

This video is gold. Been trying to understand this flow for years, and finally, this video did it for me. Thank you!

[@NTFAQGuy]

Glad it helped!

[@JonathanAtherton]

You are right, I did have to watch this twice, It all clicked towards the end of the vid & made a lot more sense the secondtime round. Awesome Thank you :)

[@jonmac9077]

Absolutely fantastic, I read numerous documents over the space of a week and this video explained the equivalent of hours of reading in a 30 minute video and made it a lot simpler to understand, brilliant, thank you :)

[@NTFAQGuy]

You're very welcome!

[@cb98678]

THANK YOU! Your video should be a mandatory course for anybody entering devops

[@christierney5322]

This really is fantastic. The Microsoft docs are really hard to grok, and this was exactly the information I needed. Bravo, and thank you so much.

[@NTFAQGuy]

I'm glad it helped make things clearer!

[@sukhsingh19]

Explained very complex topic in very lucid manner. Thank you for creating such awesome content!

[@NTFAQGuy]

Glad you liked it!

[@shaul47]

A lot of things got clear in my head after watching this video! I like your teaching style, very clear, concise, and one that keeps your attention. I'll surely watch other videos. Thank you John, appreciate it!

[@NTFAQGuy]

Thanks, glad you liked it.

[@samhouston2000]

your videos are so good that as soon as you say " If that was useful, please like". I feel compelled and obligated to drop everything and smash that like button. You are one awesome teacher. I am also a teacher like you, I go as far back in the history as it is needed to establish a strong foundational understanding. Thanks for being you.

[@NTFAQGuy]

Wow, that is so kind, thank you

[@dirkl9652]

It's very obvious that you enjoy teaching Azure. I hope I can get to this level of understanding Azure. Keep up the great work.

[@NTFAQGuy]

Thanks, I do. good luck.

[@cdm297]

One of the best explanations so far on the internet, Thank you John

[@Threep666]

This cleared up a lot of confusion I was having for how the Azure apps work, now I know what the difference is between the apps and the enterprise apps finally, thank you!

[@NTFAQGuy]

Great to hear!

[@saiganapathyswaminathan910]

This has to be the best explanation of Azure App Directory and its working.. Thanks John.

[@NTFAQGuy]

Happy to help

[@saiganapathyswaminathan910]

​@@NTFAQGuy BTW John. I have an app registered in my AAD. It is a confidential multi-tenant application. I couldn't find any proper doc explaining the process to make my app available publicly for other tenants (Release). Or isn't there any such thing as release ?. I can just share the installation URL so that the other tenants can access my application. Won't there be an validation by the MS team ?. Any help on this.

[@behman904]

This is the best and very clear explanation of these complicated concepts. Thanks so much John.

[@NTFAQGuy]

Glad it was helpful!

[@mayankparihar1988]

Very nicely explained. Perfect to watch 2 time and you understand all about app registration and oauth 2.0

[@chinchi4293]

Very well explained, you should write the documentations for Azure, I read and read and haven't fully understood it. But now, I got it! Thank you very much. It really helped me.

[@robbiejames1466]

Great summary at the end. I'll probably need to watch this again but certainly something is starting to click

[@Lamukra]

A damn eye opener... jeez, finally I got the answer I was looking for! A lot of kudos to you! Subscribed and following :)

[@dscoduc]

Great video, thank you. Are you planning on doing a deeper dive into this topic? There are many more pieces to this part of Azure that are difficult to understand, such as the difference been App Registration tokens and Enterprise Application tokens, SAML (RP) configurations, API access permissions, etc.

[@anandchandrashekhar2933]

The quality of your content is amazing. Thank you!

[@NTFAQGuy]

Very welcome

[@Navii_24]

After basking in the concepts that you poured out in this video, just made my day. Thanks a lot for this video John.

[@NTFAQGuy]

Glad it was helpful!

[@felipemenesesdittel6799]

Such great content! You really make a difference in making IT content widely available. Greetings from Costa Rica :)

[@NguyenTung-go9cb]

Someone said: If you can't explain it simply, you don't understand it well enough I was enjoying this video just like eating a piece of cake. Not only this video, but all your channel is also saving tons of time for our world lol. Cheers buddy

[@NTFAQGuy]

Glad you enjoyed it!

[@harishmathanan3596]

A complex topic made simple and understandable. Thank you John 😊

[@NTFAQGuy]

[@sivasrimakurthi206]

love the way you explain the concepts, loved it always John. Thanks!!

[@Mikael_Puusaari]

This is such a good explanation of it, there were a few parts that were only buzzwords and nothing else for me and this really put the pieces together for me in a territory where I haven´t felt all too confident before, thank you!

[@NTFAQGuy]

Glad it helped!

[@soumyarahul007]

Very useful and complicated topic. Thanks for breaking the complicacy and make it easier to understand.

[@NTFAQGuy]

Very kind, thank you!

[@fabioandreteles]

Thank you John for the great video - was reviewing this yet again to grasp the concepts correctly. A quick question: when the user consents to an application (third party) using their Entra ID credentials, and the application asks for the consent, this will create the SP in the user's tenant only, that will have the scopes set? I'm thinking for example Gmail, or other third-party email client that the user might use - did I understood this correctly? Just trying to make this all clear in my head. Again, great stuff - with added knowledge in the last 2 years, I understood more and more of this! Great stuff!

[@KhawajaDaniyal]

Phenomenal explanation @john savill. I'm exploring creation of a Shared Image Gallery to be used other tenants, and couldn't fully grasp the 'why' behind the app registration. Your video gave me the understanding I needed.

[@NTFAQGuy]

Great

[@dronacharya6527]

Always been confused on this topic, what a clear and simple explanation . Thanks a lot❤.

Thank you so much. i have been very struggling to understand these topics and your video really make my dots connected to line. I will for sure re-watch it a few times to deepen my understanding :)

[@TridibChowdhury]

Thank you for this explanation! I'm a UX designer who was curious about what my scrum team developers meant whenever they mentioned 'service principal' amongst themselves. Now I know 👏🏼

[@NTFAQGuy]

You are so welcome!

[@MelodiqueMyst]

Loved it, thanks for explaining it in layman terms. I have been working on AAD for sometime but never was able to wrap my head around Application Registration and Service Principal.. 🙂👍

[@NTFAQGuy]

My pleasure.

[@G3CK0S]

This is how you teach. I'm shocked, man. Fantastic work and thank you.

[@NTFAQGuy]

My pleasure!

[@chandrag2536]

Thanks you Savill... while I understood the nuances of OAuth 2.0 flows and the AppID, SP and Managed Identities, could not tie them all together... this is really good. Thank you

[@HornOkay]

Thank you so much for a great explanation. My Thoughts: You have combine Oauth explanation in general with this video. *In my opinion, it can much simpler by explaining - what is Application in Azure, App Object, Scopes and Service Principal. And on top of that how client can connect Resource via Service Principal. That would hold much more value in my opinion.*

[@NTFAQGuy]

This is just how I think it best to explain but sure there are many others and different approaches may work better for sure.

[@HornOkay]

@@NTFAQGuy i agree, thanks again for a great video.

[@JaiPrakash-pq1pj]

Thanks Jhon for the tutorial video. As you initially said if you learn why then how part becomes easier. Completely agree and the way how you dissect and explain its very good of you. Cheers

[@NTFAQGuy]

Glad it was helpful!

[@ec0321]

That's really an awesome work. Concepts are well articulated. Could you please explain more on back channel and front channel logic. That would also help us understand clearly why client receives code and then token separately due to security concerns.

[@NTFAQGuy]

That really comes down to oauth and the capabilities of the client if it’s capable of the back channel (although now nearly all clients are capable of some form)

[@michield6812]

Very good presentation. I'll have to rewatch this a few times though to grasp all of it. Thank you!

[@darshank]

This is really helpful session. I really appreciate your efforts for creating it in depth.

[@erhanballeker6383]

Thanks for the great content. I just wanted to make tiny addition/correction (but what i believe its important especially when trying understand these cryptography related things :) ), when the pkce added to code grant flow, first, client sends the sha256 hashed -cipher- of random string that its generated (as you said in the video) and then from the backchannel it does not sends the cipher again, it sends the plain text string generated in the beginning(with tls secured) and delegates it to idp to hash it with sha256 and compare the two hashes and understand that if its the same client. The video is great as always, thanks for sharing these kind of qualified contents.

[@NTFAQGuy]

Cool, thank you for sharing.

[@Dalj-Puma]

Studying for my AZ-500, this video really helps. Thank you John!

[@NTFAQGuy]

Best of luck!

[@Itsnarak]

Explained wonderfully!! Easiest explaination I have come across. Thank you for the content.

[@NTFAQGuy]

Glad it was helpful!

[@KurtInTampa]

First off thank you for the very good walkthrough. Most people don't touch this topic. We are updating a largish document management enterprise solution we sell to others for on premise install, but want to move to Azure AD and the Key Vault to for authentication and storing of secrets. I'm having a hierarchy conundrum. Do we create a new Active Directory Tenant, with all new app registrations for our APIs and Clients for each new customer? Most online examples show those tenant, registration and audience IDs as hardcoded. Seems like a lot of complexity creating different binaries for the same pieces of our solution for each install (and update)... Thanks, Kurt

[@NTFAQGuy]

It’s not a simple answer as depends on your app, is it multi-tenant etc. you likely need to get a consultant to go through detailed requirement gathering to give right guidance.

[@KurtInTampa]

@@NTFAQGuy Spent 30 minutes this morning with someone MS's Azure team subcontracts with. Was more confused after than before. Will probably have to try it again with someone else. It's not Multi tenant by the definition I understand. Other than aggregating exceptions in the cloud for management purposes. A separate copy of the same binaries and SQL DBs with the same structure (and their own content) would exist exist at each location with their own private documents siloed there.

[@ranadebpramanick469]

Thank you John. One of the best, crystal clear explanations i have heard so far. Until i watched this, i was under the impression that App Registration and SPN are synonymous :). Your way of teaching in whiteboard make things crystal clear. Hopefully some time in the future your pluralsight videos will also have the same format.. :)

[@NTFAQGuy]

That is very kind, thank you. I don’t think pluralsight will want me teaching on the whiteboard but who knows :) I try and supplement here in the KZbin ;)

[@nuwansamarasiri7364]

Great Explanation about App Registrations and Enterprise Apps. Thanks John!

[@Insane2030-y8j]

Thanks for breaking it down..I had to watch it twice :-)

[@louisapplewhaite506]

Still the best video on azure app authentication

[@jasonracey9600]

I'm here because I suddenly need to set up Enterprise Apps, App Registrations, and App Roles for microservice intercommunication and the Azure terminology alone doesn't help me understand the differences between these resources. I'm also trying to understand where Service Principals and Managed Identities fit into all this. Thanks for the great explanation of the underlying athn/authz process.

[@NTFAQGuy]

I have other videos about auth including one on unattended auth where I cover managed identities and service principals.

[@mhlaskar1991]

Thanks a lot, John for the hard work. It really pays off. I have one doubt, so for every user of the app(client), will there be a service principal? I guess no. Also What's the relationship between AUTZ token and SP?

[@NTFAQGuy]

No sp per app in the tenant. Sp represents the client in flow.

[@dosto-evsky]

Thank you Sir, very useful explanation how services work behind the scenes, it has some basic similarities for authentication as with your lecture about ADFS, tokens, xaml and cookies, how different servers communicate, easy enough to follow, a good little condensed/concise session.

[@NTFAQGuy]

Thanks!

[@SuppersReady8880]

Very helpful explanation, and well presented, love how you used the virtual whiteboard, very effective and dynamic visual aid. I'm trying to resolve how AppRoles work and how to get the "roles" attribute that OIDC can pass back to populate based on mappings of "Users and Groups" (say a group) to a specific application role defined by a developer within a multi-tenant app.

[@NTFAQGuy]

Glad you liked the video! Thanks for watching

[@tommyrong6955]

This is the best one I have see.

[@dn8153]

great tutorial, on your diagram labeling the Client as "Client App" would help to provide clarity. Once you mentioned "Client App" things became clearer

[@NTFAQGuy]

haha, sadly can't go back in time and change :-)

[@aramosjr03]

Hi there! Thanks so much for the very informative presentation. Watching it for the second time now. 🙂 Unfortunately, I got a bit lost when you mapped the components in your scenario at the beginning to the Azure AD components. Is the App1 that you're registering the client or the resource? Assuming it's the client, then do we need to register the resource APIs as well so we can associate them during the client app registration? I might have missed those steps.

[@NTFAQGuy]

The App would be the client that wants to consume the resource you own.

[@aramosjr03]

John Savill thank you for the prompt reply

[@elvirkaric1449]

John - finally watch this video today, very good and detailed explanation of SP in AAD. One question - do you think that Azure Automation Account is also Service Principle?

[@NTFAQGuy]

right there is no such thing as azure automation account in AAD :-) its just a service principal that its managing for you :-)

[@JNolan1124]

Another great video. Thank you for such a great explanation :)

[@MexMario]

Amazing explanation, thank you . One question: Do we have to do any kind of configuration in the "API", something like saying "I want to give access to App1"?

[@NTFAQGuy]

You delegate or set at app for the apis

[@MexMario]

@@NTFAQGuy I guess that would be your next video 😀?
