We are building a Web App/API to publish in our Azure AD and want to provide access to the app by inviting (B2B scenario) external users into our Azure AD. This will create accounts in our Azure AD of type "Guest" which we will use to assign permissions to the app. In this scenario, do we need to configure our application to be "multi-tenant"? There are steps to take inside the code to accommodate for multi-tenant sign-ins and there is a setting on the Settings tab of the App Registration in Azure AD that is labeled "Multi-tenanted" where you select either Yes or No. On the App Registration setting, there is a pop-out bubble that says:
Designates whether users in external organizations are allowed to grant your
app access to data in their organization's directory
I am not sure how (or if) the code changes and the app registration setting are related but our app will not need access to any data outside of our directory.
No your app does not need to be multi-tenanted and you do not need to direct users to the /common endpoint. I have tested this, and you still get a kind of SSO experience.
Example paul#org1.com (homed in Org1 AAD) is a guest user in Org2 AAD (invite has been accepted). Now this same user opens a private browser and logs in to Org1 AAD.
The user then tries to hit a web app with app registration in Org2, and web app redirects user to https://login.microsoftonline.com/org2.onmicrosoft.com/oauth2/authorize.
Result, user is considered logged in by AAD and gets redirected to the redirect_url with tokens, etc.

We are developing a multi-tenant application that is hosted in Azure. We're using IdentityServer4 for handling authentication and authorization. Recently, we enabled the SSO by registering our application in Azure AD. We enabled the multi-tenant SSO in the App registration service. The SSO works fine and client users can sign in with their Azure AD.
The users are accessing the application by providing the URL in the following format https://myapplication.com/mytenant. When a user logs in for the first time consent is required and if accepted the user can successfully log into its tenant space.
After the first successful access, our application is added to the My Apps portal in Azure.
Our problem is that the URL in My Apps is pointing to the one provided in the Branding tab in App registration but not the one that the user logged in for the first time. Since this is a multitenant application every tenant has its own URL.
Is it possible for the first sign-in URL to be saved in the My Apps portal? We can do an Azure tenant - application tenant sync based on claims but that means a lot of trouble just for accessing the My Apps portal.
An administrator of each customer could add a linked "single sign-on" app in their organization and assign it to users, but there's no way to have your single multi-tenant app present in different tenants with different URLs.
What you could do instead is to have your (only) sign-in URL be a URL that triggers a sign-in (generically, on the "common" or "organizations" endpoint, instead of a tenant-specific endpoint). Once the user has signed in, then you'll know what tenant the user belongs to, and you could redirect them to the appropriate version of your site.
I am trying to setup Azure AD integration with our partner identities. I have few providers that I need to support and they support SAML and WS-Fed. I am trying to use Azure AD External Identities to add these providers to my Azure AD tenant.
However, reading through this article, it seems like SAML integrations are invitation based.
I want users to be able to login without an invitation. How can I do this with Azure AD?
Here are my needs:
After adding the external idp, users should be able to login using their own credentails via their idp. No additional information needed to use an app.
I should be able to grant them access to custom apps (mandatory) and azure resources (optional)
Choose what idp's are allowed per app? (if possible)
Thanks in advance.
Question 1: After adding the external idp, users should be able to login using their own credentials via their idp. No additional information needed to use an app.
Answer:
We can implement Guest users redemption using direct link or a common endpoint instead of email invitation. A guest user clicks the app link, reviews and accepts the privacy terms, and then seamlessly accesses the app.
Using Common endpoint : Guest users can now sign in to your multi-tenant or Microsoft first-party apps through a common endpoint (URL), for example https://myapps.microsoft.com. Previously, a common URL would redirect a guest user to their home tenant instead of your resource tenant for authentication, so a tenant-specific link was required (for example https://myapps.microsoft.com/?tenantid=). Now the guest user can go to the application's common URL, choose Sign-in options, and then select Sign in to an organization. The user then types the name of your organization.
Using Direct Link: As an alternative to the invitation email or an application's common URL, you can give a guest a direct link to your app or portal. You first need to add the guest user to your directory via the Azure Portal or Powershell Then you can use any of the customizable ways to deploy applications to users, including direct sign-on links. When a guest uses a direct link instead of the invitation email, they’ll still be guided through the first-time consent experience.

Question 2 : I should be able to grant them access to custom apps (mandatory) and azure resources (optional)
Answer: Add the Users as Guest to Azure active Directory but by default they will be sent an invitation even if they don’t open it you can assign an app in your enterprise application for them to use .
Most federated applications that support SAML 2.0, WS-Federation, or OpenID connect also support the ability for users to start at the application, and then get signed in through Azure AD either by automatic redirection or by clicking on a link to sign in. This is known as service provider-initiated sign-on, and most federated applications in the Azure AD application gallery

Quickstart: Add guest users in the Azure portal - Azure AD
To Provide the Guest user access to azure resources you can manually add a role to the users.
Question 3: Choose what idp's are allowed per app?
Answer: Create different user flows and add desired IDPs to the user flows and then assign applications registered in Azure AD to the user flows depending on which IDPs are needed for given application.

Question 4: I added Okta as an External Identity using SAML in my Azure AD. Created an "App Registration" as multi-tenant. But I am getting this error.
AADSTS50020: User account 'xxx' from identity provider 'http://www.okta.com/xxxxx' does not exist in tenant '' and cannot access the application '0000000c-0000-0000-c000-000000000000'(Microsoft App Access Panel) 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.
Solution: Please Ensure User is added to one of the Partner Admin Groups i.e. AdminAgents in the Partner tenant.

Question 5: Steps for setting self service signup for an application.
Test Scenario in my Lab
Azure AD with an application registered in application registrations blade.
Another AD tenant with users.
Step 1: In the above external identities collaboration settings please make sure to have enable guest user self service enabled.
If it is not enabled then you can’t create a self service flow and you will get the below error when a user from other tenant is trying to access the app.
Step 2: Create a user flow by going to the user flow blade and creating a new flow.
Step 3: After you have created the user flow , click on the User flow and go to application blade and click add application.
Now search for the application you want to provide the self service signup to and click on select and you will have now enable the self service sign up for users when they try to access your application.
Output:
Once the above settings are done you can access the url to your app. Provide the user of the different ad tenant and you will get output as below .Click on create a new one .
Once the user from other AD tenant have accepted it they are successfully registered as guest users in your tenant.
If they accept the above then they will be able to access the app from now as a guest.
We are currently building an headleass application (without front end). This app has to be run as deamon and need to update calander entries of user in different tenant.
We have our seperate Azure subscription where we have created a VM and hosting app. we have different Azure AD tenant thatn the target tenant. I was thinking of registrating the app in our tenant as multi-tenant app. But then I am not sure how it will authorise to change resurces in another tenant.
Or it is must for app to be registered in target tenant?
One of the most important thing is we dont want interactive admin consent flow, as we want everything to be an automatic process. None of the document explains the significance of tenant ID in authentication flow. Anybody knows anything ?
First, you need to create a multi-tenant application in the original tenant, and then grant the application the Calendars.ReadWrite application permission.
Next, run admin consent url in the browser, and then you need to log in with another tenant's administrator account and consent. The multi-tenant application will then be added to the target tenant as an enterprise application. https://login.microsoftonline.com/{tenant-id}/adminconsent?client_id={client-id}.
At the same time, the application will have the Calendars.ReadWrite application permission in the target tenant. Finally, you only need to use the client credential flow to obtain the token and then call the Update calendar api to change the calendar entry of another tenant.
I'm trying to create an app hosted in Azure that (should) allow public login, as long as you have a Microsoft account. I don't care if it's a business or personal account. You just need to be able to log in. I'm creating a SPA and an API.
So I went to the Azure portal and created an app registration and configured the app reg to allow all users from within, or outside the organization with a valid personal or business Microsoft account.
Now the SPA is an Angular app and I use Damien Bod's OpenId library to log in. When I point the stsServer to my login endpoint (https://login.microsoftonline.com/{my-tenant-id}/v2.0) and log in, all works fine, except when I log in using an account outside the organization (for example my personal account).
I get receive the following error:
AADSTS50020: User account 'xxxx#xxxx.xxx' from identity provider 'https://sts.windows.net/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx/' does not exist in tenant 'Default Directory' and cannot access the application 'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx'(App Name) 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.
Now the problem is that I simply don't want to add all these users, but allow them access to this app. How can I do that?
Thanks a bunch!
If you want to allow any account to sign in, you can't use your tenant-specific login endpoint.
You need to use the "common" endpoint: https://login.microsoftonline.com/common/v2.0.
This allows login with any Azure AD / Personal Microsoft account.
I have created a Web application in my local Azure AD which I can successfully use to authenticate members of my AD tenant with (using oAuth2 flow). Now I need to extend my supported scenarios to allow a global admin from an external Azure AD tenant to sign-up their company to use this application as well.
Based on the Microsoft Docs this scenario, Multi-Tenant, is supported...
Authentication Scenarios for Azure AD
Multi-Tenant: If you are building an application that can be used by users outside your organization, it must be registered in your company’s directory, but also must be registered in each organization’s directory that will be using the application. To make your application available in their directory, you can include a sign-up process for your customers that enables them to consent to your application. When they sign up for your application, they will be presented with a dialog that shows the permissions the application requires, and then the option to consent. Depending on the required permissions, an administrator in the other organization may be required to give consent. When the user or administrator consents, the application is registered in their directory. For more information, see Integrating Applications with Azure Active Directory.
From my reading it appears that at some point a global admin for the foreign tenant should be presented with a URL which they can follow ( login.microsoftonline.com/common/??? ) which will somehow cause the external application to precipitate like a morning dew into their Azure AD. However, if this is the correct approach I would appreciate a tokenized example of how one correctly builds the login URL for a multi-tenant external Azure AD application which a group admin can follow to allow access in their AzureAD.
Ok, through trial and failure I have found the solution. The group admin for the remote tenant needs to be provided with the following URL which will allow them to register your Azure AD application as an Enterprise Application in their tenant.
https://login.microsoftonline.com/{remoteTenantUrl.com}/adminconsent?client_id={YourAppsClientID}&redirect_uri={YourAppsCallbackPage}
