We need Azure AD application permissions to be set for the scenario below.
There are multiple CLient Apps calling the Supporting App.
The Supporting app's role is to create abstraction around the Web API calls to make the Client apps light.
The problem is we need to track which Client app made the call when the call comes to the Application WebAPI from the supporting App.
How should we register our applications in Azure AD to make it possible?
Do the ClientApp need to add application permissions to Supporting App and Application WebAPI ?
Do the ClientApp need to add permission to Supporting App only and Supporting App needs to add permission to Application WebAPI?
• Since the client apps will be accessing the supporting app for specific tasks or calls or doing some function, the client apps should have access to the Supporting app’s API and data flow accordingly. The client apps should have permission to the supporting app’s API to call the web API through it. Thus, you would need to create ‘App roles’ and assign scopes to the client apps for accessing the supporting app API and further on, create ‘App roles’ and appropriate scopes to access the Web API from the supporting app.
• Thus, you would need to register each of the client apps, supporting app and the Web API to be accessed through the supporting app in Azure AD. Once registered, please ensure that you have created the required ‘App roles’ for each client application and the client application is given permission to access the supporting application with the required scope through the ‘Application permission’. Also, ensure that the supporting application credentials are included in the requests sent to the supporting app to access the Web API through it. Similarly, you would need to configure the above in supporting application API in Azure AD.
Please find the documentation link below which explains the above steps in detail for adding permission to access a Web API: -

I'm really struggling with these Azure AD concepts.
Here is my situation. I have a webapp with users belonging to Companies. I have a requirement that is to be able to authenticate those users through their Companies' Azure AD. Eventually, We would want to offer this in the Azure app gallery in the future.
I started registering the app through App Registration, which gives me the information to integrate using OIDC. We would like to support both, OIDC and SAML protocols (I see that there are apps in the gallery offering both).
I tested OIDC out and it's working correctly, but when I want to develop SAML integration, the documentation says that it has to be done using an enterprise application. I can't edit the SSO section of the enterprise app generated by my registration:
The single sign-on configuration is not available for this application in the Enterprise applications experience. MY APP was created using the App registrations experience.
so I tested creating a new enterprise app. Using this app I can do all the SAML flow correctly.
My questions here are:
Do I have to connect the registrated app with the enterprise app? How I do that?
Why I can't edit the SSO info in the enterprise generated app?
If it's done through the registration app. Where do I set up the SAML endpoints, certificates etc.?
By reading the docs, I understand that enterprise apps are like "an instance of a registered app". That leads me to think that I should configure all in the registered app, but I can't see how to support SAML.
As mentioned by #Srinath Menon in the above answer, If the application was registered using App registrations then the single sign-on capability is configured to use OIDC OAuth by default. In this case, the Single sign-on option won't show, For enterprise applications we have an option.
In both the ways applications are get registered in AAD, and there are two types of objects get created once the app registration is done.
The Application Object is what you see under App Registrations in AAD. The application object describes three aspects of an application: how the service can issue tokens to access the application, resources that the application might need to access, and the actions that the application can take.
. App Registration are basically the apps local to the tenant/organization.
The Service Principal Object is what you see under the Enterprise Registration blade in AAD. Every Application Object would create a corresponding Service Principal Object in the Enterprise Registration blade of AAD. A service principal is created in each tenant where the application is used and references the globally unique app object.
Enterprise apps blade shows global apps (other tenants) which can be configured and used within your tenant/organization.
Reference
Set up SAML-based single sign-on for an application
No, there is no specific reason to connect the 2 apps.
The reason for this is by default "App Registration" is wired for OIDC Auth. https://learn.microsoft.com/en-us/azure/active-directory/manage-apps/configure-saml-single-sign-on
This need to be done from the Enterprise apps for any SAML related functionality.
I have created an Xamarin Android App with an Azure App Service back end. When I looked at securing the connection, I don't really care about individual users, but I want to make sure that only someone running my app can access the database. Is there a way to authenticate the app itself rather than individual users? What is the best practice in this scenario?
If you don't care about user, there are a few approaches and the security level may vary. If you want to simplify integration and deployment among Azure services, you should consider using Azure AD as an identity and access management in your entirely system. That said, your back-end and Xamarin app are authorized and authenticated via Azure AD. You need to register your native app in Azure AD which you can refer here https://learn.microsoft.com/en-us/azure/active-directory/active-directory-application-proxy-native-client
Another approach is to use certificate-based authorization against Azure Active Directory, which is more controlled and security rather than client secret. In this case, persons installing your app must also install certificate before sending request to Azure App Service and retrieve database from Azure SQL Database. The level of authorization is free of choice, but the first gateway is always Azure AD.
I have running the basic todoitem app service running on azure. Calling the below url will display the content in the todoitem table. How can I add basic security to prevent this data from being accessed by anyone, like a basic parameter, ToDoItem?MyToken=12345.

I would recommend you using the build-in Authentication and authorization in Azure App Service.
App Service supports five identity providers out of the box: Azure Active Directory, Facebook, Google, Microsoft Account, and Twitter. To expand the built-in support, you can integrate another identity provider or your own custom identity solution.
Here are some great tutorials, you could refer to them:

I am currently use a multi-tenanted application, and have authentication working for a single azure AD. I would like to have multiple ADs connected to the authentication of the authentication page. How can I do so from within the Azure administrator console?
If I understood your question: you setup a multi-tenant app in the properties of the application in Azure, but currently your application only accepts user of one tenant to sign-in.
If this is the case, then what you have to do is to also adjust your application's code to be multi-tenant. In order to enable multi-tenancy on your application:
Double check you have set Multi-Tenanted property to Yes on your application registration's information in the Azure Portal (by default, applications created in the Azure Portal are configured as single-tenant)
Update your code to send requests to the 'common' endpoint (update the endpoint from https://login.microsoftonline.com/{yourtenant} to https://login.microsoftonline.com/common)
For some platforms, like ASP.NET, you need also to update your code to accept multiple issuers
For more information about multi-tenancy, see: How to sign in any Azure Active Directory (AD) user using the multi-tenant application pattern.
We have an API, we planning to publish this API in the Azure marketplace under developer service. For authentication, we are planning to use developer service SSO (Single sign-on) in API. I googled this but can't find any useful link, please suggest some links
Azure AD B2C became generally available recently and it somehow offers what you are looking for. You can use local Azure identity and/or social account for your end users to authenticate with SSO support.
https://azure.microsoft.com/en-us/services/active-directory-b2c/
With that being said and although you can secure your Web API with AAD b2C as in this guide, your customers won't be able to call this WebAPI from their own applications as the calling app must be registered in the same Azure AD directory with the same application Id. This is a limitation that is mentioned here:
Note:
Azure AD B2C currently supports only web APIs that are accessed
by their own well-known clients. For instance, your complete app may
include an iOS app, an Android app, and a back-end web API. This
architecture is fully supported. Allowing a partner client, such as
another iOS app, to access the same web API is not currently
supported. All of the components of your complete app must share a
single application ID.
If the above limitation is OK with you, then you might also be interested in this Azure article to list your app in the Azure AD application gallery.
