one of our existing projects is running with a traditional authentication logic (having a user table in database). How the plan is to move the identity to AzureB2C with social IDPs integrated. But there are still some ares where we would need the reference of the existing user table. I need to find a way to map the logged in user from Azure B2C with the user table in database. I can read the email property from claims and try to map, but the challenge is user might have a different email for his social accounts. I know this actually defeats the purpose of the openId/oAuth to look back again in the user table after login. But this is a strange situation in running into. Any ideas how best this can be done ?
Copying response from: https://social.msdn.microsoft.com/Forums/en-US/221fce11-28ff-4236-a300-d6160ffc9379/azure-ad-b2c-how-to-map-the-user-logged-in-from-social-idp-to-a-local-user-table-?forum=WindowsAzureAD
Some facts are missing from your question so I will make assumptions which you can correct.
Assume that:
You do not use social IDPs today. So no existing connection between the social account and the local DB account.
This point is crucial because it is usually the user's prerogative (due to privacy) to make this link explicitly.
Assume that you will tell the user explicitly what you are doing as part of the transition.
To achieve this with b2c built-in policies you could:
1. Your app logs in the user the old fashioned way.(existing lookup DB)
2. Your app then invites users to register (in fact re-register) using a b2c signup policy which offers them social idp choices.
3. At the end of the b2c registration process, the user's email which was provided and proofed during the b2c signup and Object ID (newly created) is sent back to the App
4. The app uses the object ID and Graph to write the users existing id (old DB email or other unique user id you used today) to the new user's object in Azure AD B2C.
5. The app should note on the old DB that this user has been migrated so in the future the app does not present the option to re-register.
6. The app has to manage users in 2 different states.
Other alternative is to use custom policies and Account Linking
Here you could
1. Migrate all users into b2c using their old passwords. (assume you can get them from old DB in the clear) using Graph.
2. Point your app to b2c - users can login
3. Offer you users the option to link their b2c account to a social account. this requires custom policy and a policy path that is not public but its a simple sample we can provide.

Currently our team is struggling with propper architecture of Azure B2C solution for our multi tenant app.
Here is what we want to achieve. We want to enable users from certain Azure AD to authenticate. This is nicely described here with restricting tenants we want to enable.
We just want to enrich this solution with google authentication. We do not want to enable all users to be able to sign up. Is there a possibility to create google federated user programatically? We basically recieve list of emails from customer company and we create accounts in tenant). As far as I know there is no possiblity to achieve this using ms graph API when I don't have issuerUserId of user.
Do we have any possible solutions for this type of scenario? Like invitation email or so? Or maybe B2C is not a propper solution in this case.
Thanks in advance
A solution would be create the allowed users in b2c as a local account in graph api with accountEnabled as false and some generated password. Since the accountEnabled is false, user will not be able to sign in or reset the password as the default set of custom policies verify that attribute.
In the federated flow in custom policy,
Let the user complete federation.
Read the account using email address received.
If a local account exists, then link the federated account (Write alternateSecurityId to the account using objectId).
If a matching local account cannot be found, block the user by showing a selfAsserted page saying you are not allowed to sign up/in to this application.
You could also have some custom boolean extension attribute set to the local account to have an extra validation and update it's value once user completes the signup.
We want to use Azure AD as the Identity Provider for users in a web application. At the moment, we have everything set up using MSAL.js 2.0 with the Auth Code Flow, a custom scope, and access token which is used to authenticate requests towards our various backend services.
The issue is that our users want to be able to login with their own custom email addresses, instead of their login ids generated by AD and with the #onmicrosoft.com domain. For example, user1#some-orginization.com or user2#some-other-organization.
It would still be okay to accept the login ids as usernames as well, but surely there must be a way to allow users to use another property of the profile (their alternate email for example) to log in.
Our application is registered to AD such that it will allow only logins from one tenant, since we don't want to require users to already have existing Microsoft Accounts.
We're avoiding B2C because some users would face issues with their company policies, which would mean they could be invited as users, but would be rejected at login. Also, B2C does not really support Roles like B2B does, which is somewhat important for us.
Any guidance will be greatly appreciated.
EDIT:
After countless hours of attempting to make this work, I decided that it just isn't worth the effort, and switched to Auth0. They provide everything I could possibly want, and seemingly even better Azure AD integration to other tenants then Azure AD itself.
I think what you want to express is that you want to log in to your application with any email (including personal accounts and social accounts).
If so, then you need to modify the application's manifest configuration and then change the /tenant id endpoint to the /common endpoint.
To change the setting for an existing AD App, navigate to the Manifest blade of it in the portal, find the signInAudience attribute, set it with AzureADandPersonalMicrosoftAccount or PersonalMicrosoftAccount.
Kick tires around. We want use Azure B2C for identity management for our web application that embeds PowerBI. PowerBi Embedded and the application are on a separate tenant that is used for our organization. Can this still be done?
You could use Embed content for your customers, also known as App owns Data.
User logs in using Azure B2C
Application back-end will verify user log-in and receive user details
Application back-end should generate embed token. This means that you need to understand how to link a B2C user to a report id / role etc. You can do this in your back-end based on metadata or a table lookup.
You can also include the username and roles if you would like to use Row Level Security (RLS).
I want to integrate Multi Factor Authentication (MFA) through Azure Active Directory (AD), I checked its documentation and some code samples, then I knew that Azure AD B2C have some of features which suits my requirement,
NOTE - I only need MFA feature from Azure AD B2C,
I tried this sample code provided in official docs, https://learn.microsoft.com/en-us/azure/active-directory-b2c/active-directory-b2c-tutorials-spa
But I have some of queries:
1) Is there any service in Azure B2C, which can directly provide MFA facility to integrate, without need to register users in Azure AD?
2) In Azure B2C, can I control user flow with information of my website? So that email and phone number will be of my website during user flow. (I am asking about this because according to my plan I am going to integrate it after login process in my website)
3) There are 3 types of account in Azure B2C, (Work account, Guest user, Consumer user), Which user type is most suitable? (I only need MFA for the user, and will require to manage users via Graph or any official API)
4) From where can I decide, which type of user will be registered? because the code which I have tried, doesn't mention about user type, (Actually I want to know that is there any param or option in user-flow, which can decide type of user, which will be registered through this flow)
Any help or suggestions will helpful for me,
Thanks in advance,
1. Is there any service in Azure B2C, which can directly provide MFA
facility to integrate, without need to register users in Azure AD?
Yes you can restrict new user to sign and sign up using MFA. For that need to enable MFA. Its global MFA for all.
See the screen shot below.
Note: You can also implement MFA for each individual user.
See the screen shot below for Individual MFA
Once you implement MFA you would be prompted to verify your phone
number like below
Note:
For Testing MFA Userflow need native application on application
drop down
See the screen shot below
2. In Azure B2C, can I control user flow with information of my
website? So that email and phone number will be of my website during
user flow. (I am asking about this because according to my plan I am
going to integrate it after login process in my website)
Yes you can customize your user flow. You can add new user flow according to yours.
To do that, Choose All services in the top-left corner of the Azure portal, and then search for and select Azure AD B2C
Then In the left menu, select User flows, and then select New user flow
See the screen shot below:
3. There are 3 types of account in Azure B2C, (Work account, Guest user, Consumer user), Which user type is most suitable? (I only need MFA for the user, and will require to manage users via Graph or any official API)
In short Work account has the more privileged in B2C tenant as the official document says. As consumer account cannot access some resource on portal. For accessing Microsoft Graph API Guest user has some restriction even on azure portal.
Note: As per your requirement I would suggest you to go with Work account which has some benefits while you would access Microsoft API
Though the account type mostly depend on your business needs but Work Account more useful comparing all aspect.
Let's say, If you want to add some user those who already registered some other organization but you need to add them in your particular application privilege. So need to add user as Guest privilege.
4. From where can I decide, which type of user will be registered?
Tough the question is bit confusing as I said earlier it would depend on your business needs. Work account usually best for tenant user. So when you feel within on your tenant if new user need to add so go with Work account. Once you specify your need it would definitely easier for you which kind of user you need to add. There is no such reference which can explain well upto to now.
Note: You could try adding all the user type to check how the user account behave using portal and accessing resources.
I would like to pre-register a limited number of users which can use my application.
This are the requirements:
Users should be able to reset their password on their own
No other users than the preregistered users can sign up
Ideally, the user can choose the login email address by himself (no #app.onmicrosoft.com login).
Now I'm having trouble to have all requirements fullfilled together.
I was able to preregister #app.onmicrosoft.com users in the Azure Portal. But since the user can't get emails on #app.onmicrosoft.com, a password-reset-policy would not make sense. I tried to specify alternate-email and a phonenumber in the user-profile, but unfortunately the password-reset-policy is not using it for verification.
Let's say I create a sign-up policy: This is nice - the user choose his own email. Password resetting would also work. However, I can't control who's signing up and getting valid access tokens. In the portal, under Enterprise Applications, I found my registered application (All Applications) where I can set an option "User assignment required?" to true. But this does not seem to work in the B2C context, right? I expected, that until I assign a user to this application, the user is not getting a token on sign-in, but this wasn't the case. Here I found a similar question about creating users. Any advice on creating users including passwords etc. using Microsoft Graph (since it's recommended to use it over Graph API)?
I also tried to invite users as guests. They have to create a microsoft account, resetting passwords would be solved through microsoft, but unfortunately, no redirect to microsoft login happens after entering the microsoft account email address.
Deleting the signup policy after initial registration is a bad option if more users have to be onboarded.
Ideally, I would like to preregister users as if they signed up by their own - but with no signup policy.
Any advice? What do I miss?
You can implement the activation/invitation scenario that is described here and implemented here.
This scenario activates/invites a new user by creating/pre-registering a local account in the Azure AD B2C directory through the Azure AD Graph and then sending a signed redemption link to the email address for this local account.
This redemption link directs the new user to the Password Reset policy.
Currently creating users in a B2C tenant with a "local account" is not supported in Microsoft Graph. For this you'll need to use Azure AD Graph for now (see creating a user with a local account). Please see this blog post for details and line item 12 in the table.
We hope to add this capability as soon as we can to Microsoft Graph.
Hope this helps,
