We are currently using Azure Access Control Services (***.accesscontrol.windows.net) to allow customers with personally-managed Microsoft Accounts (Identity Provider) to sign in to our customer self-service portals (Relying Party Applications), which are Angular apps powered by Web API services. In our Access Control Services we are currently passing through the nameidentifier http://schemas.xmlsoap.org/ws/2005/05/identity/claims/nameidentifier claim from Windows Live ID to the relying party APIs, which match that token to an identity in our applications.
We are looking to support both Enterprise and Personal Microsoft Accounts with the Azure AD v2.0 service, but do not understand how to migrate our existing users to the new system. The code examples suggest that the OWIN middleware returns the NameIdentifier claim from the user's Identity Provider, but if that Identity Provider is the same Microsoft Account (aka Windows Live ID), will that be the same NameIdentifier we are currently receiving via Access Control Services pass-through?
Any help and/or documentation that clarifies how this transition is intended to work would be appreciated.
If the nameidentifier coming out of ACS is the randomly generated value then you're kind of stuck because that value is unique to the ACS/RP/User. If it's returning the actual Live ID then it'll obviously only match if the Azure AD user has the same email address.
I don't know if any documentation out there that describes how to handle this situation. My recommendation is to just require a one-time authentication from each source within the same session and marry the two results. That would basically mean
authenticate to Azure AD
Your app: Hey you don't have any user details, do you want to associate a Live ID?
Authenticate Live ID
Associate Live ID with Azure AD
Then if they want to sign in with either accounts in the future you have a link between the two.

We have Gsuite account where we created a OAuth 2.0 Client IDs (picture below) in order to implement our client application to users for Single sing on using (Using OAuth 2.0 for Web Server Applications: https://developers.google.com/identity/protocols/oauth2/web-server). Is this ClienId sufficient to have in order for any private gmail domein to have access to our app thru sso? Is there a limitations of domains our app might have linked to this clientID? many of our clients have their own Gsuite account, but since we host the application, I imagine they don't have to create a clientID for every single gsuite account right? I tested and with different domain outside of our gsuite account and it works. I was just wondering what could go wrong in terms of limitations of domains or users?
Thanks guys appreciated.
I need help integrating Azure AD B2C and Google APIs. Briefly, I created a tenant on Azure AD B2C, policies and a Native App. Users can register to my app and sign in without any problems. Now I need to use Google APIs to access the logged-in account's information and manage some information (Google MyBusiness data). How can I achieve that. Is that possible ?
Furthermore, even if that is not connected to Azure AD B2C, how can I request to the user to accept that my app to view MyBusiness data?
UPDATE: I understand that I need to authorize my app to https://www.googleapis.com/auth/plus.business.manage Google scopes. Is it possible to request that scope during Google SignIn application authorization process?
Thanks everyone.
As part of the authentication exchange between Azure AD B2C and Google (as well as other identity providers), an access token is issued by Google for use by (and only by) Azure AD B2C, where this access token is used by Azure AD B2C to access the authorized information for the authenticated end-user.
Currently, Azure AD B2C does not pass this access token through to the relying party application (i.e. your native client application), therefore applications can't access the information for the end-user.
UPDATE on 20 June 2019
Using a custom policy, you can pass the access token from the external identity provider through Azure AD B2C to your relying party application.
From the official Azure AD B2C FAQ:

Can I configure scopes to gather more information about consumers from various social identity providers?
No, but this feature is on our roadmap. The default scopes used for our supported set of social identity providers are:
Facebook: email
Google+: email
Microsoft account: openid email profile
Amazon: profile
LinkedIn: r_emailaddress, r_basicprofile
Newbie question here on Authentication. I am used to incorporating authentication into my app backend server, like Spring Security Authentication for example. I don't really understand how the authentication providers work.
My concern is that somehow each provider can only authenticate its own accounts, ie google can only authenticate for gmail accounts, and Azure Active directory can only authenticate some kind of Microsoft registered account? I am disinclined to oauth because as a user I am always paranoid about signing in for some game or app from an unknown provider becacuse I never am sure whether I just gave my gmail or facebook account password to a rando.
I am fine giving people the option to use Oath, but less comfortable if that's the only option. I would like people to be able to give me whatever email address they want, and a password which they create for my site only.
Also these questions: If I use an authentication provider can I get the actual email address being used to log in? Or do I only get a token?
If I am going to build my own authentication service so I can accept any email domain as user name, what is the easiest to implement in Xamarin forms, and can somebody point me to a tutorial or something?
Advice appreciated thanks.
Yes, you're right, each identity provider provides the ability to authenticate their own users; Google OAuth supports Google accounts, Azure Active Directory supports Microsoft work & school accounts, Microsoft Account supports Microsoft personal accounts, and so on.
You have quite a few options on how to add support for these identity providers in your app, in addition to what we typically call 'local accounts', or accounts created specifically for the given application. I'll list out a few approaches:
You can write all the code yourself to integrate with each identity provider individually, and build-your-own local account solution as well.
You can use an SDK/library in your Xamarin Forms which facilitates using multiple identity providers within your app. The Xamarin.Auth package has historically served this purpose for Xamarin apps. It provides auth capabilities for Facebook, Google, Microsoft, and Twitter.
You can use a dedicated cloud service which provides authentication services for your app. Some examples include Azure Mobile Apps, Firebase Auth, Gigya, and more. The exact identity providers supported and the level of support for Xamarin/Xamarin Forms will vary across each one. Azure AD B2C is another option that I know supports Xamarin Forms as well as Facebook, Google, Twitter, and local accounts (disclaimer: I work on AAD B2C). These services sometimes have free tiers & paid tiers, so you can compare & contrast each.
You could also build your own authentication service using open source code like Identity Server if you wish.
It definitely depends which route you go, but generally speaking each solution will provide you access to some user profile information upon user authentication. For Azure AD B2C, you can configure the claims that are returned to your application in the tokens your app receives. For other services, you may need to make a REST API call to get some user data like the email address.
HTH.
I'm building mobile applications using .NET. What I'm looking for is a way to manage user sessions and info using Azure Mobile Services. I've read a lot about the authentication in Azure Mobile Services, but this only authenticates a user via Facebook, Twitter, etc ... to access azure services.
I'm looking for user session management, i.e. register, login, logout. Be able to save and retrieve user info, i.e., save certain info against the user such as age for example. Also session management and caching, i.e. the user will remain logged on when the app is closed and re-opened. Also azure mobile services doesn't seem to provide a way to allow me to register users via email.
Basically, If anyone is familiar with Parse, I'm looking for having similar functionality in Azure. Can anyone help please ?
Thanks
Out of the box, Mobile Services provides easy authentication with social providers (Facebook, Twitter, etc) and Azure Active Directory. If you want to do registration via email, you'll have to create a custom auth system. This is going to be more complex than just flipping a switch and using Facebook auth, but totally doable and I can point you in the right direction. First, check out this post that will explain how you can create a registration / login system using custom API and the script backend. If you're using a .NET backend, you'll need to alter thing a bit (the samples are in JS) but it should be pretty easy to convert. The only piece that is really missing from that post is how to do email verification. To do this with Mobile Services, I would suggest the following.
Sign up for a SendGrid account (free in the Azure store)
From your script, after registering the user, generate a random alphanumeric string that is saved to their account / user record in the table.
Use the same string to create a URL which you can send to the user's email address (check out this tutorial for sending email via SendGrid and Mobile Services).
The link can either go to a different custom API or a web front end. When that endpoint is hit, it should update the user record to show that they have verified their email address.
I'm converting an existing Google Apps Marketplace app to support OAuth2.
I understand the use of access keys to identify the user account but how can this be used to link a user to a 'company' or 'domain'?
Our app supports having multiple user logins under one business account - we need to be able to identify what company a user belongs to using OAuth2. How can this be done? (we're using C#).
Is there an additional user API that needs to be called after initial authentication, if so, which one? (we're using C#).
