Current situation: symfony application with authentication via azure AD B2C.
How is it possible to make an authorize check to [https://TENTANT.b2clogin.com/TENTANT.onmicrosoft.com/oauth2/v2.0/authorize via ajax to verify if a customer has an active session on azure AD, i only need to retrieve the azure oid from the token.
Now i redirect the user to [https://TENTANT.b2clogin.com/TENTANT.onmicrosoft.com/oauth2/v2.0/authorize?p=B2C_1_sign_in&client_id=CLIENTID&none=defaultNonce&redirect_uri=REDIRECTURI&scope=openid&response_type=id_token&prompt=login&response_mode=form_post&ui_locales=en but i want to get rid of that.
You can use MSAL method ssosilent(), which opens the auth endpoint via hidden iframe. That succeeds only if there is a valid session cookie at AAD B2C. Note this only works if your app and AAD B2C are on the same root domain name.

We have integrated keycloak with Azure Active Directory and integrated it with a few applications.
We have a few applications that are directly integrated with Azure Active Directory. Is there an approach I can follow to make a person logged in to one application to be signed in all the other applications irrespective of the authentication provider used (keycloak or Azure AD)?
Normally I'll be logged into all applications integrated with keycloak if I signin into one application integrated with keycloak and vice-versa with Azure AD.
Your requirement can be fulfilled with the app service feature by leveraging the token store and authorization behavior of the configured authentication providers for the apps configured. But only tokens received from keycloak can be forwarded to Azure AD for authentication purposes and further sign in respectively to all apps registered with Azure AD. The reverse is not possible as keycloak doesn’t has the ability to forward the sign in token request received for the application configured back to Azure AD for authorization.
You will have to enter the REST API code for signing in and out of a session accordingly by incorporating the below likewise code in your environment.
Log in with the Microsoft Identity Platform
Log in with Facebook
Log in with Google
Log in with Twitter
Log in with Apple
Please find the below documentation for an approach on forwarding the authentication tokens from Keycloak to Azure AD for access authorization: -

Thanking you,
I'm trying to use AWS Cognito with a user pool using Azure AD as an Identity Provider (OpenID Connect).
I set up the User Pool in Cognito and specify the callback URL of my test app (https://localhost:44381) and I configure an App Registration in Azure AD that has the same URL in the Redirect URIs.
In the AWS Console, under App Client Settings, I click "Launch Hosted UI" to test it. It displays a page that lets me choose my configured Identity Provider (Azure AD). On that page, I can see in the URL what it has for "&redirect_uri=". It has https://mydomain.auth.us-east-2.amazaoncognito.com/oauth2/.
So I put that URL in both AWS Cognito and in Azure AD as the Callback URI/Redirect URI.
Then when I click through to the Identity Provider, it pops up the normal Azure AD login and lets me log in, but I get:
AADSTS50011: The reply URL specified in the request does not match the reply URLs configured for the application: '60e47fff-e2cc-41d8-8405-283bafb33fbb'.
This is the application (client) ID from Azure AD.
Likewise, when I run this from my test app, I can see the redirect_uri=https://localhost:44381/oidc in the URL - but same thing happens - redirect mismatch. Though that exact URL is in both AWS and Azure AD.
How can I find out what it is trying to "match"? It's obviously changing something in the URL that I give it.
I'm trying to integrate Azure AD B2C with my App Service using the Authentication / Authorization menu in the portal (also called EasyAuth).
This is what I did:
Registered the application in Azure B2C
Recorded the App ID
Defined user flows (just Sign In)
Set up identity provider (Azure AD)
Tested the user flow, with Redirect URI pointing to jwt.ms, to see the result - works fine
Enabled Authentication / Authorization in the App Service in the Portal
Configured Azure AD authentication with the App ID from above and the link to the endpoint metadata
But now, when I access the App Service, I'm redirected to a "Logging in..." page which immediately goes to the jwt.ms page, with no JWT data, no login page, and no opportunity to enter my credentials.
Just an empty jwt page.
I couldn't find anything in the docs that can explain this.
What am I missing?
Completely new to B2C. Tried both of these walkthroughs, but I'm missing something still:
https://github.com/Azure-Samples/active-directory-b2c-advanced-policies/blob/master/Walkthroughs/RP-SAML.md
http://blogs.quovantis.com/saml-based-sso-with-azure-ad-b2c-as-an-idp/
Both of these only describe the policies needed, but I'm pretty sure I need to register an app on B2C still? The problem I have with app registration is that SalesForce gives me a token endpoint URL with a query string:
https://mycompany.cs79.my.salesforce.com/services/oauth2/token?so=00D1h000000Cnli
And B2C won't allow query strings in the reply URL.
Is there any way around this? Salesforce also supports OpenID I think, if that would be better?
::::::::::::UPDATE 6/22::::::::::
SAML:
I found and realized I was missing a critical step on the SalesForce side: adding the authentication provider to my domain's login page. Clicking the new link redirects me to B2C, but I get an immediate error from B2C. Application Insights shows the following exception:
The SAML technical profile 'serviceProviderMetadata' specifies a PartnerEntity URL of 'REMOVED', but fetching the metadata fails with reason 'For security reasons DTD is prohibited in this XML document. To enable DTD processing set the DtdProcessing property on XmlReaderSettings to Parse and pass the settings into XmlReader.Create method.
OpenID:
Using this write-up as a guideline, I've registered the app in B2C and configured the SalesForce side.
Instead of using the Azure AD authorization endpoints, I pulled my B2C tenants endpoints from my meta data URL (login.microsoftonline.com/{tenant}/.well-known/openid-configuration).
This works for my B2C admin account, however, when I try try a test user that isn't a B2C admin I get the following error from the B2C sign-in page:
Sorry, but we’re having trouble signing you in.
AADSTS50020: User account 'REMOVED' from identity provider 'LINK REMOVED' does not exist in tenant 'MTB2CTest' and cannot access the application '5c8b9f4f-cf28-42fe-b629-b87251532970' 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.
::::::::::::UPDATE 6/23::::::::::
OpenID:
I’ve found that it works 100% only for my B2C admin account if I don’t use a policy, but doesn't work for other accounts. When I use a policy, only accounts that signed up through the policy can authenticate with B2C (which is great) – but the token doesn’t seem to be reaching SalesForce. I've created two PDFs showing the configuration details and the results from each method (policy and nopolicy) here.
Both of these only describe the policies needed, but I'm pretty sure I need to register an app on B2C still?
Not exactly, you no need to register an app at B2C side. All the configuration you do in Policies is enough.
Did you try Salesforce SAML SSO article https://help.salesforce.com/articleView?id=sso_saml.htm&type=5
Check the above article and try to do configurations at Salesforce side and grab the details required by SAML RP
I hope by following both SAML RP and Configure SAML Settings for Single Sign-On articles you can configure B2C as IDP for Salesforce.
I stumbled on this question while trying to implement Azure AD B2C as an IdP for Salesforce. We used Open ID Connect to enable SSO between the two. This involved setting up an Application in Azure AD B2C, enabling the read scope on that application, and configuring the connection in Salesforce using that application, a custom policy returning a JWT token, and a dummy User Info endpoint.
Check out this answer for exact steps on how we set up Open ID Connect: https://stackoverflow.com/a/61639332/13484109
Sign-in with Microsoft identity provider fails, works with others
I have an Azure AD B2C tenant with a SingIn and SignUp policy that I hope to use
for user management with an Angular2 SPA.
The policy is configured for three identity providers:
Google
Microsoft
Email Signup
When I use the Run Now button in the Azure portal to run this policy, I get the default Sign In dialog, and I can sign in with either Google or Email signin. (By that I mean I get re-directed to my app's redirect page as I expect.) However, when I try to sign in using the Microsoft
provider, I end up at an error page with the following address:
https://login.live.com/err.srf?lc=1033#error=invalid_request&error_description=The+provided+value+for+the+input+parameter+'redirect_uri'+is+not+valid.+The+expected+value+is+'https://login.live.com/oauth20_desktop.srf'+or+a+URL+which+matches+the+redirect+URI+registered+for+this+client+application.&state=StateProperties%3deyJTSUQiOiJ4LW1zLWNwaW0tcmM6NDcyMmQyNjItOTk1Yi00YTJlLWFmNWUtODkwNDgyODlhMzM0IiwiVElEIjoiM2Y2ZDVmNjAtMDdiNC00ZDA3LWEyZDItN2U3YWQwOWRhOGQ5In0
I see that the problem is related to an invalid redirect_uri. But I thought the redirect_uri was an application-level setting shared by ALL identity provders that I have configured. Why does my redirect_uri setting work for Google and Email signup, but not for Microsoft?
You have to configure your Microsoft application with the right redirect URL.
As stated in the documentation:
Enter https://login.microsoftonline.com/te/{tenant}/oauth2/authresp in the Redirect URIs field. Replace {tenant} with your tenant's name (for example, contosob2c.onmicrosoft.com).
Why you have to do this: (courtesy of Chris Padgett)
The redirect URI that is configured in the Azure AD B2C Portal represents the reply address for your client application. This is so Azure AD B2C can return an ID token to your client application. The redirect URI that is configured in the Application Registration Portal represents the reply address for your Azure AD B2C tenant. This is so the Microsoft Account identity provider can return a security token to your Azure AD B2C tenant.
So, your app is federating authentication to Azure AD B2C.
B2C then further federates to the Microsoft Account identity provider.
So when a user a logs in with a Microsoft account, they are sent back to B2C with a token, which B2C validates.
If all is okay, they are signed in to B2C, and sent back to your app.
So you see that from the point of view of the MSA identity provider, B2C is the client.
So the redirect URL there must point to B2C.
As the document stated, you should Enter https://login.microsoftonline.com/te/{tenant}/oauth2/authresp in the Redirect URIs field.
But I thought the redirect_uri was an application-level setting shared
by ALL identity provders that I have configured. Why does my
redirect_uri setting work for Google and Email signup, but not for
Microsoft?
You're right, the redirect_uri is an applicaiton-level sttings. It should be same in all IDPs redirect URIs. But this Redirec URI is set by Azure. NOT your applicaiton. It means that your can use other IDPs to login to your app with AAD B2C, NOT login to your applicaiton directly. So, the redirect_uris must be https://login.microsoftonline.com/te/{tenant}/oauth2/authresp, not the redirect_uri in your application itself.
URI doesn't equal URL. The redirect URI is just a unique identifier to which Azure AD will redirect the user-agent in an OAuth 2.0 request. It's not redirect URL, Azure AD authentication endpoint https://login.microsoftonline.com/ use redirect URIs to check where it should be responsed. Aslo, it can be same as the URL as the endpoint. Here should be the same I guess.
Summary, you need use the unique redirect URI https://login.microsoftonline.com/te/{tenant}/oauth2/authrespfor all IDPs , not just Microsoft account.
Hope this helps!
