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

End-user experiences for applications - Azure Active Directory
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.

I'm developing system where any user can login through Microsoft Azure SSO.
I have done following
Create B2C tenant (Initially tried B2B)
Create enterprise application
Set "AzureADandPersonalMicrosoftAccount" for "signInAudience"
Setup SSO with SAML using "https://simplesamlphp.org/"
Now everything is working fine for my account. But if I trying with other personal user (which I haven't added as guest user in my tenant), then it returns error
User account 'user#domain.com' from identity provider 'live.com' does not exist in tenant 'xxxx'
and cannot access the application 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.
I want any personal Microsoft user can login through SSO (without adding it as guest user in tenant).
Thanks in advance!
I tried to reproduce the same in my environment and got the below results:
Please note that, if you are creating Enterprise Application in Azure AD b2c Tenant it will be authenticated via Azure Active Directory only not Azure AD b2c.
When I tried to login through Personal Account, I got the same error as below:
As Enterprise Applications authenticate via Azure AD, it is not
possible to authenticate users with personal Microsoft accounts
without adding them as Guest Users.
The only approach is that you add them as Guest users and login to SAML SSO without invitation.
Go to Azure Portal -> External Identities -> External collaboration settings -> Enable guest self-service sign up via user flows
On the left blade, Click on User flows -> New User Flow,
Once the user flow gets created successfully, click on the user flow, select applications and add your application like below:
And try signing to your application with Microsoft Personal Account.
I have a requirement where we want the users to use their social accounts to login into our application (i.e. get an ID Token) through Azure B2C. I configured the Identity Provider and create a user flow for Sign in only. We don't want Users to Sign Up because that through Invitation only. When I use the "Invite User" to the live.com account and the user accepts the invitation and tries to login into the application, I get the below error.
AADB2C99002 User does not exist. Please sign up before you can sign in.
But the user is existing as a Guest User.
When I allow Sign up and the user actually does the Sign-up and then login in, it works.
Questions:
Why isn't the Guest User allowed to access the application? What needs to be done for the same to work?
If it's not possible, I don't want the user to be a "member" to avoid maintaining their credentials. I want the users to use their social accounts only.
As I don't have the requirement of self sign-up and the only invitation-based, how do I achieve my requirement?
Thanks,
Neel
Please see the Overview of user accounts in Azure Active Directory B2C.
Guest account - A guest account can only be a Microsoft account or an Azure Active Directory user that can be used to access applications
or manage tenants.
Consumer account - A consumer account is used by a user of the applications you've registered with Azure AD B2C. Consumer accounts
can be created by:
The user going through a sign-up user flow in an Azure AD B2C application
Using Microsoft Graph API
Using the Azure portal
Guest account is specifically distinguished from Consumer account. So Guest user can't sign into B2C application directly.
Your three questions are actually the same question: How to log in a social account without managing its credentials?
Please refer to Add an identity provider to your Azure Active Directory B2C tenant.
In order to let live.com account sign in, you need to Set up sign-in with a Microsoft account using Azure Active Directory B2C. Choose the policy type (User flow or Custom policy) you want to find the corresponding steps.
If you need your customers from other social idps such as Facebook, Google and so on, you can find the corresponding article on the left.
Log into Azure B2C
Click Users
Select a user
Click Applications
I created users in my B2C tenant by logging into my website using various OAuth identity providers. So for any user selected using the above steps I expect to see at least one application listed - that being the one the user signed into when their user record was created in Azure.
When I perform the above steps I only see applications listed under my own user name. I created all the users I see in my tenant so I know there should be apps listed with each user name.
More formally stated my questions are:
Given an Azure AD Application, how do I get a list of users that are authorized to log into that app?
Given an Azure AD User, how do I get a list of applications that user is authorized to log into?
I would like to accomplish the above tasks using Azure portal - I don't want to write script. Also, my purpose in asking these questions is to be able to delete or disable users as needed.
Azure AD B2C does not hold a mapping of Users who signed into an App to a specific Application Registration. By default, all users are authorized to sign into your apps if you have OAuth IdPs configured against the AAD B2C policy that allows authentication to your App.
You can use the AAD B2C Sign In logs to see which users have been logging into what applications.
Assigning or not assigning Users to Apps in the Azure Portal does not enforce any authorization, this is an Azure AD only concept and doesnt apply to Azure AD B2C.
The process you followed(Users->select user->application) will only be able to see the applications listed under your tenant.
In the same manner when you choose an application and select the users/Groups you will only be able to see the users who have accessed your application.
Based on application/user->application you can remove the access from that application.
Regarding the
Given an Azure AD Application, how do I get a list of users that are
authorized to log into that app?
Given an Azure AD User, how do I get a list of applications that user
is authorized to log into?
The list of users/application authorized details are completely depend on the application consent flow.
Application developers can dictate what types of permissions are being requested and if they want to guide users through the user consent flow or the admin consent flow. If the application is provided with user consent flow based on the consent acceptance any user can access that particular application.
Admin consent flow is when an application developer directs users to the admin consent endpoint with the intent to record consent for the entire tenant. Application access grant to the requested data on behalf of the entire tenant.
For more details on the consent and permission please go through the document
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}
We are designing an application which will be used by client's employee, some of their vendors and consumers as well. All of these three types of user will have the different set of rights.
We were analyzing the Azure AD and found that Azure B2B can be used for employees and vendors whereas B2C can be used for consumers. So, we need both of them. Can we setup our application in such a way that if can authenticate from B2B and B2C both? Or any other suggestion to implement this.
Thanks In Advance
You can totally setup an app to authenticate with multiple directories.
Setup one Azure AD that will be used by employees, where partners can be added through B2B. Then also setup a B2C directory for the customers.
On your app side you need to display a choice for the user: if they want to sign in as an employee/partner or as a customer. Then you redirect to the correct sign-in page.
You'll need to define the app twice, once in both directories.
The actual implementation will vary based on your tech stack, but in ASP.NET Core you would need to setup multiple Open ID Connect middleware. And none of them can use AutomaticChallenge, as you do need to know where to redirect the user, you can't really choose for them.
Update to B2C allows you to do it all from there now
Azure AD B2C now allows custom policies (preview feature). This means you can use any OpenId Connect provider for sign-in, including Azure AD of course.
This new feature allows you to:
Create a B2C tenant with custom policy for employee/partner login through Azure AD
Send all users to authenticate with your B2C tenant
Users can choose if they want to sign in with social accounts or if they are an employee or partner
If they choose to sign in as employee or partner, they would be redirected to your Azure AD
In the end your app gets a token from B2C telling where the user signed in, so you can then do authorizations based on that info
