I have configured Azure B2C as IDP via SAML successfully for a single Service Provider. There are many pieces that i don't understand in this setup even though its working.
I will describe what i have so far and then ask questions later.
Let's say I have two Service Providers,SP1/SP2 both require SAML and a page to signup/signin. SP1 requires loyality_id as custom attribute and SP2 requires product_name attribute.
Here's the source code that works.
Credit/Thanks to this blog
Below is the high level summary of the configuration.
SAML for SP1 (Service Provider 1):
Add signing and encryption keys to the B2C tenant
Register Identity Experience Framework applications
Create web app IdentityExperienceFramework in Azure Active Directory
Create native app ProxyIdentityExperienceFramework in Azure Active Directory
Start from starter pack for LocalAccounts as base
Add Saml2AssertionIssuer to the base policy
Add user journey SignInSaml to the base policy
In Extension Policy override "Local Account SignIn" claims provider and add substitute values for "client_id" and "IdTokenAudience" from apps that were created earlier
Policy file with RelyingParty for SP1
This describes the output claims that are added to the SAML response
Signup/signin policies for SP1:
Create built-in signup and sigin policy
Create Application in Azure B2C blade
So far with this setup, I have two Applications in Azure Active Directory for custom policies and one Application in Azure B2C blade for built-in policy.
According to https://learn.microsoft.com/en-us/azure/active-directory-b2c/active-directory-b2c-create-custom-attributes-profile-edit-custom,
Extension properties can only be registered on an Application object
even though they may contain data for a User. The property is attached
to the application. The Application object must be granted write
access to register an extension property.
What is the "Application" the above paragraph is referring to?
What is the purpose of the apps IdentityExperienceFramework/ProxyIdentityExperienceFramework
To setup for SP2, do I need to create separate Azure Active directory apps for IdentityExperienceFramework/ProxyIdentityExperienceFramework? Or can I use the same ones? How do custom attributes factor in this?
How do I setup custom attributes in this case where SAML is through Custom policy and Signin/Signup is builtin policy
In this case, under what App context are the custom attributes created?
I appreciate any pointers.
Thanks
The application is the one created in the section "Creating a new application to store the extension properties".
The apps purpose is to enable sign-in using local accounts. The same apps can be used accross multiple policies.
Custom attributes are related to the application created in app registrations at Azure AD level, and with the permissions detailed in the configuration docs.
In my Github profile, you can find a different implementation of the B2C as SAML issuer scenario: https://github.com/marcelodiiorio/My-Azure-AD-B2C-use-cases.
Tell me if you have more questions.

We installed an enterprise application through the Azure AD App Gallery. But when we try to config the Single Sign-on, it keeps saying:
The single sign-on configuration is not available for this application
in the Enterprise applications experience. HubSpot is a multi-tenant
application and the application is owned by another tenant.
Do we need to change some settings to allow the setup of Single sign-on?
We followed this tutorial but are now stuck on "Configure Azure AD SSO".
When added the hubspot application from Azure AD Enterprise application gallery like below ,you should be able to see if SSO setting is available or not and the ways it can be supported for sso.(Here i can be able to use SAML based SSO, or linked SSO)
Then you should be able to edit the saml configuration
For me when I search the hubspot app created in app registrations, its under supported account type of my organization only.
Please check if the App is registered and added as Multi-Tenant App in your case and users have to use login for particular tenant instead of common to avoid error.
Also user accounts need to be pre-provisioned into HubSpot prior to
sign-in .

I am using Aure AD B2C to connect a .Net core application with Azure AD Enterprise application for authentication using SAML protocol. I am using custom policies to enable SAML.
I have used custom policies starter pack given in Microsoft Docs, and authentication is working properly with given name, surname, name, IDP as claims and I want so additional claims that my application is using.
I need DOB and MemberID as claims for my application and there was no option to add custom claims to the active directory where my enterprise application is.
I have another IDP setup in Okta and luckily I could add custom claims like DOB and MemberID to user profile in Okta but still I am unable to get those claims after authentication.
This is an Azure AD question.
The problem is that DoB etc. is not part of the schema.
If you are using Azure AD Connect and these attributes are in AD, you can use directory extensions to synch them up.
You can synch them up to extensionAttributes that are in the SAML drop-down.
Then add them as outputs in B2C.
If not, you can add extension attributes to Azure AD and use a custom policy REST API that calls Graph API (either directly or via Azure function) to get them.
Also refer this.
I am trying to create an AAD App Registration that includes additional claims in the JWT tokens that are returned to the client application.
The idea is that a SalesRepID fields need to be added to each of the AAD users. Then the SalesRepID be included in JWT claims through application manifest configuration.
Is this possible? What are the steps? An article or a code sample that shows how to do this would be a great help?
It's possible.
1) Add custom attribute by using Register an extension. (Please note that it only supports v1.0 application)
2) Set values for custom attributes.
3) Modify application manifest of the Azure AD application and return the extension property as claims.
Besides, Microsoft strongly recommends that you use Microsoft Graph instead of Azure AD Graph API to access Azure Active Directory resources. For how to add custom attribute to Azure AD user with Microsoft Graph API, please refer to: Add custom data to users using open extensions.
Scenario:
(Azure-hosted) Web App. Users should be able to sign in to my app using a Microsoft Account (i.e. #live.com, #hotmail.com, etc accounts) that has one or more Azure subscriptions. The application would then allow them to view and manage their Azure resources in specific ways through my app.
Points of confusion/frustration:
ADAL vs MSAL for authentication
Azure AD vs Azure AD B2C for the tenant hosting the application
Where do you register the tenant app? In the AD B2C under "App Registrations"? In a regular AD under "App Registrations (Preview)"? On the App Registration Portal (i.e. apps.dev.microsoft.com)?
Which of the above client ID & secret do you use in the web app (in the .config file)?
The documentation for none of these seem to cover the scenario end-to-end and most of it is completely out of sync with other developments.
I am hoping here to get some point of guidance from other developers that have actually gone through this journey themselves (rather than folks that just read the documentation). In specific, I am hoping to get answers from the Azure CXP team that monitors these questions and provides official & supported answers.
Your scenario requires access to Azure APIs, thus you have to make the logins against "regular" AAD, not B2C.
You can't make your logins against MSA accounts directly as they must be members of an AAD to have access to subscriptions.
You can use either ADAL or MSAL to handle the authentication.
Note you must use v2.0 endpoint for MSAL and the "v1" endpoint for ADAL.
See limitations of the v2 endpoint here: https://learn.microsoft.com/en-us/azure/active-directory/develop/azure-ad-endpoint-comparison.
You register it under Azure portal -> Azure Active Directory -> App registrations.
You can also use the preview version if you want.
You will need the application id (= client id) + a key (secret) from the app registration.
I'm trying to use Azure AD B2C as a SAML Identity Provider.
I am aware that several locations on the web state that B2C does not (yet) support SAML as identity provider (also e.g. answer on this question: Can I integrate a SAML application with Azure AD B2C?).
However, when I read the comparison between built-in policies and custom policies on the "Azure AD B2C Custom Policies" docs, I see that SAML is already supported today as an identity provider.
Also, I found this GitHub walk through: https://github.com/Azure-Samples/active-directory-b2c-advanced-policies/blob/master/Walkthroughs/RP-SAML.md
Following that walk through, I have an issue in step 5 "Upload Certs" of the first section "Create the SAML Token Issuer" while executing New-CpimCertificate.
I can successfully import the module ExploreAdmin.dll. However providing my credentials while calling New-CpimCertificate, I get this error on the console:
New-CpimCertificate : Unauthorized.
Access to this Api requires feature: 'Advanced' for the tenant: '<myazureb2ctenant>.onmicrosoft.com'.
Any help, thoughts, comments... are very welcome!
Azure AD B2C still does not officially support (even in preview) connecting with apps via SAML (aka being a SAML identity provider).
It only supports connecting to other identity providers via SAML (aka being a SAML relaying party).
The GitHub walk through you came across is an old walk through before the official launch of the Azure AD B2C Custom Policies preview. It talks about features that weren't included in the scope of the preview, such as B2C as a SAML IdP. It also references tools (those PowerShell scripts) and steps that are no longer applicable.
The mention of SAML in the Identity Providers section of the "Azure AD B2C Custom Policies" doc refers to supporting B2C being a relaying party that connects to a SAML Identity providers, not the other way around (where B2C is the SAML identity provider itself).
All that being said, you CAN make your scenario work, with the clear understanding that it's not supported.
You can use that GitHub document you've referenced, swapping out the steps that involve ExploreAdmin and New-CpimCertificate for these instructions that allow you to upload the certificate via the portal:
Go to your Azure AD B2C tenant. Click Settings > Identity Experience Framework > Policy Keys.
Click +Add, and then:
Click Options > Upload.
Enter a Name (for example, YourAppNameSamlCert). The prefix B2C_1A_ is automatically added to the name of your key.
To select your certificate, select upload file control.
Enter the certificate's password.
Click Create.
Verify that you've created a key (for example, B2C_1A_YourAppNameSamlCert).
