Lookup user information in Microsoft Graph from a console app - azure-active-directory

I want to lookup people Name and email address using their ADID/SAMAccountName/UPN from a console app running with its own credentials and not under my account.
How would I do this with Microsoft Graph?
I was following up on https://github.com/Azure-Samples/active-directory-dotnet-daemon-v2 but that seem to require admin access. (BTW is there an easy way to figure out the admin on my company's graph?)
I did lookup LDAP querying but domain limitations limit the search scope ,and would rather do this via Microsoft Graph.

Accessing Microsoft Graph without user credentials (i.e. using the OAUTH client credentials flow) requires Admin Consent for your application. Typically this consent would be handled by your IT department.

Using personal account (live.com) to get an access token for my app

I am having trouble getting an access token using the password grant auth end point.
I created an app registration in my Azure account which is tied to my personal live.com Microsoft account.
In the application settings I've set the supported account types to AzureADandPersonalMicrosoftAccount (Accounts in any organizational directory (Any Azure AD directory - Multitenant) and personal Microsoft accounts (e.g. Skype, Xbox))
When I attempt to to authorize via my personal account's username/password using the https://login.microsoftonline.com/{{TenantId}/oauth2/v2.0/token end point using grant_type=password I get the following error:
AADSTS50034: The user account {EmailHidden} does not exist in the xxx-xxx directory. To sign into this application, the account must be added to the directory.
I am not sure how this is possible as I am obviously the only member of my Azure AD.
The app, Todo Inventory is listed under the applications in the user profile as shown below:
Note that I am successfully able to get an access token using the auth code flow described in the documentation here: https://learn.microsoft.com/en-us/azure/active-directory/develop/v2-oauth2-auth-code-flow
But I want to use the password grant instead but nothing I tried seem to be working.
Am I missing something here..?
Microsoft identity platform doesn't support resource owner password flow for personal accounts. https://learn.microsoft.com/azure/active-directory/develop/v2-oauth-ropc
The Microsoft identity platform endpoint only supports ROPC for Azure AD tenants, not personal accounts. This means that you must use a tenant-specific endpoint (https://login.microsoftonline.com/{TenantId_or_Name}) or the organizations endpoint.

Why does Microsoft Dynamics 365 ask for delegated admin in Azure app registration

I'm following a guide online to generate an access token to access Microsoft Dynamics 365 Customer Engagement: https://eax360.com/dynamics-365-online-connect-using-postman/.
All of it works fine, however I am wondering why delegated Admin permissions need to be supplied in Azure Active directory during app registration. I have seen a lot of guides explain that permissions must be delegated but the above site documents the process well. As a general rule, I thought that starting with the lowest security permissions was the norm. I am new to Azure AD so thoughts are very much welcome.
If your app will be a client which allows the authenticated user to perform operations, you must configure the application to have the Access Dynamics 365 as organization users delegated permission.
Application permission means that you want your app to access Common Data Service without a user.
So whether to use delegated permission in Azure app registration depends on your needs. It is not mandatory.
But we can see that the Application permissions in Azure app registration is gray out. This is because Microsoft provides a different way to implement it.
We need to create a Common Data Service application user an then bound it to the registered app. After that, we could connect using the application secret. See the details here: Connect as an app.

Need to update contacts on user's Microsoft Outlook, do they really need to have an Active Directory?

Every documentation or tutorial I follow on how to programatically access Outlook's API seems to point to the same pattern:
Application redirects user to Azure so he can authorize (OAuth) the app access to his account's data.
Every time Azure Active Directory is mentioned as a cloud-based credential/access manager.
I'm having a hard time to understand why exactly AD is even needed. And even if it is, that means that should a company desire to integrate an application with the employees calendars, for example, they would need to have an AD just for authentication purposes? Does this make sense if I want to publish an application on Azure for any kind of customer?
Every Office 365 customer has an Azure AD for authentication. If you want to get at users contacts in O365 you have to authenticate using Azure AD.
If you want to get at contacts in Outlook.com, Microsoft provides the same authentication flow for Microsoft Accounts (MSA) that Outlook.com uses.
This means you can use the same authentication flow and call the Microsoft Graph to get contacts no matter if they are an Office 365 user or an Outlook.com user. Your app does the same auth flow and makes the same calls.

Lock Microsoft Graph access to only one domain

I have searched far and wide to find out how I can change the settings of my Microsoft Graph app so I only allow login from my own domain.
Since the login from Graph takes all Microsoft accounts i've been looking into different solutions, all from finding custom token endpoints to changing the application manifest.
In my manifest I can find this "signInAudience": "AzureADandPersonalMicrosoftAccount" - but I can't find in the documentation what other options there are.
also on this Microsoft page I can find this information
The overall solution comprises the following components:
Azure AD – If the Restrict-Access-To-Tenants: <permitted tenant list> is present, Azure AD only issues security tokens for the permitted tenants.
Is there any good guides online or anyone who knows how i can restrict access to people signing in either with #xxxxx.comonly or xxxxx.onmicrosoft.com accounts?
I think you're misunderstanding how Microsoft Graph works. It connects to the tenant/domain of the user authenticating. So if I authenticate with user#contoso.com, the application will only have access to the contoso.com tenant.
In terms of the authentication process itself, this is handled by Azure AD. Microsoft Graph simply accepts the token AAD returns. You can limit this process to users from a given tenant by changing the /Authorization and /Token URLs your app is using.
In most cases, apps use the /common tenant. When a user authenticates against /common, AAD handles discovering the user's actual tenant/domain and routes the request to that AAD instance for processing. These URLs look like this:
https://login.microsoftonline.com/common/oauth2/v2.0/authorize
https://login.microsoftonline.com/common/oauth2/v2.0/token
If you want to limit authentication to a single tenant, you can skip the discovery process and force AAD/OAuth to authenticate against a single AAD tenant. Only users that exist in that tenant will be able to authenticate. This is done by swapping /common with tenant's id:
https://login.microsoftonline.com/xxxxx.onmicrosoft.com/oauth2/v2.0/authorize
https://login.microsoftonline.com/xxxxx.onmicrosoft.com/oauth2/v2.0/token

Multi-tenant app in Azure AD (Active Directory) fails with AADSTS50020

I created a "Web app / API" app in our organization's "xxx.onmicrosoft.com" Azure Active Directory. The app's "Multi-tenanted" property has been set to "Yes".
We configured OpenID Connect (we use https://github.com/mitreid-connect/) to use the following URLs:
https://login.microsoftonline.com/common/oauth2/authorize
https://login.microsoftonline.com/common/oauth2/token
Please note that we used "common" in the URLs and we didn't use "xxx.onmicrosoft.com" because we want people from outside "xxx.onmicrosoft.com" to be able to authenticate and access our app.
With those settings, the people from xxx.onmicrosoft.com can properly authenticate and access the app.
However, when I use my personal live.com account (with username xxx#gmail.com) to access the app, I get AADSTS50020 error. I am able to properly authenticate with my xxx#gmail.com account, but I do not get redirected to the Reply URL. I'm stuck on Microsoft's Web page with the following error msg:
AADSTS50020: User account 'xxx#gmail.com' from identity provider
'live.com' does not exist in tenant 'xxx.onmicrosoft.com' and cannot
access the application '391e7103-ZZZZ-zz87-xxxx-7xxxxxd5xxxx' in that
tenant. The account needs to be added as an external user in the
tenant first. Sign out and sign in again with a different Azure Active
Directory user account.
What configuration do I need to change if I want people from any identity provider to be able to access my app ?
Like it has been stated here, I expected that people from anywhere could access my app without requiring more configuration on my side.
I'm asking this question because I'm in the process of getting certified for AppSource and this currently blocks me from being able to do so.
AppSource only requires work accounts to sign-in. You are using an #gmail account - which is a personal account - and because you are using the Azure Active Directory v1 endpoint in addition to common (https://login.microsoftonline.com/common), it can't accept personal accounts to sign-in directly - only work accounts.
You have three options:
If sign-in personal accounts is not a requirement for your application, then you can continue using the v1 endpoint and use a work account to sign-in/test your application. This will make you ready for AppSource certification.
If you need/ want to allow personal accounts in your application in addition to work accounts, then you can consider using the v2 endpoint (https://login.microsoftonline.com/common/v2.0) for Azure Active Directory. The v2 endpoint allow both personal accounts and work accounts to sign-in with no effort.A note is the v2 endpoint has some limitations: if you can live with these limitations (for example, your application only needs to sign-in users and eventually make queries against Graph API), then in general it should be fine to use, but if you need extra features like protecting your own Web API with scopes, then this feature is not released at this point (as November 2017). Please read this document for an updated list of limitations of the v2 endpoint.
A third (but less recommended option for AppSource) is to keep using the v1 endpoint and make your application to be single tenant - which is to change the endpoint from https://login.microsoftonline.com/common to https://login.microsoftonline.com/{yourtenantid}, and then use B2B invitations API to invite every external users (including work and personal accounts) to be part of your Azure AD tenant/organization. More information about B2B here as well.
The option '3' above have some consequences for management as well for AppSource: by using this option, you are required to have one Azure Active Directory tenant (if you don't have a tenant already, you can get one using these instructions), and the users being invited will be guests accounts of this tenant - this mean that you need to invite every external user to your application/ tenant. A multi-tenant application allows any user from any organization to sign-in to your application with less management on your side. In general for SaaS applications, multi-tenant configuration is recommended.
For AppSource, also the option '3' leads to a less-immersive user experience (Partner led trial), where the end user won't be able to access your application's demo right away - mainly because that they have to wait for the invitation's email and accept it (user has to accept being guest of your tenant) so that they can access your application.
