How to work with "Identity Management Systems"? - database

This is my first question, so I hope I don't miss a thing. To be clear from the start: I don't expect an answer which dives deep into detail. This is just about getting a general understanding of how to work with this kind of software.
So I don't know if "Identity Management System" is a suitable term for what I mean but when I talk about Identity Management Systems I think of something like Azure AD, which as far as I know provides e.g. web developers the possibility to integrate a way users can authenticate (including access privilege etc.) on their website.
What I'm quite unsure about is how to work with/ integrate such tools in a project. I will try to make it clear with an example: Assuming I have a website let's say this website is a blog. The blog consist of different posts which are stored in my own database which is connected to the website. The posts are written by different users which authenticate with a tool like Azure AD. The user's data is stored somewhere on a server run by e.g. Microsoft. If I want to display the posts togethere with the name, email.... of the user who wrote them, how would I do this?
Is it possible to query the user's data directly from the Identity Management System and display it? This does not sound ideal to me as the consequence would be that data the website uses is stored in two different locations.
Would you kind of copy the user's data from the Identity Management System to the websites database and query it from there? This does not sound like a good solution either because then data would be duplicated.
So whats the "right workflow"?
I appreciate any hints and further information I can get:-)

AFAIK To get the user's information like name, email etc. you can add these claims while generating the JWT token.
To generate access token, you have multiple authentication flows such as Authorization code flow, ROPC flow, Implicit flow.
To add the claims that you need to return with the token, you can make settings like below:
Go to Azure Portal -> Azure Active Directory -> App Registrations -> Your app -> Token configuration -> Add optional claims
When you decode the token via JSON Web Tokens - jwt.io you can find the user information that you need.
To know how to generate access token, you can refer SO Thread which I solved it before.

Salesforce Server-to-Server integration without any user involved

I am working on a integration with Salesforce using REST APIs and, as part of the project, I need to send updates to Salesforce and these updates are not user triggered, they are system triggered.
Because of that, what I expect to see on Salesforce Field History is not a user name but the name of our Connected App (the app that made the update).
What I see today is the user name because the way the integration was made initially using OAuth Authorization Code flow.
To change that part of the project, I followed the link (OAuth 2.0 JWT Bearer Flow for Server-to-Server Integration): https://help.salesforce.com/articleView?id=sf.remoteaccess_oauth_flows.htm&type=5
Making that, I was expeting to generate a token for a System, not for a User, but that's not what happened: when I used the token generate from the JWT Bearer Flow and ran the update, the Field History still shows the user name.
What could I do then?
Which are the options in Salesforce to achieve the behavior I'm expecting?
The most important, in my opinion, is to have a Token for our system, not for a user.
Thanks!
Everybody is an user in Salesforce. Even if you access unauthenticated pages (some contact us form? case or lead capture) - it gets tracked under special Guest User.
It sounds stupid but gives you unified interface to control permissions (Profiles/Permission sets). You want guests to access only FAQ articles and make cases? Sure thing, do it in profile, don't get paranoid about people trying to guess right URLs. You think an app was hacked? You can terminate the session just like any other "user". Want to allow login only in certain hours and from certain IP? Sure.
An app connecting with JWT will still need username (main difference being it's "just" certificate for signing the request instead of password).
Your best bet is to create dedicated "Mr System", "SystemX integration" account. It sounds like waste of license but in the long run saves you questions "why did you edit my account at 1 am" and you could even use it as backup account if you use SSO and it ever fails...

Azure AD B2C Direct to Identity Provider from Email

At the company I work for, we have our own Active Directory setup. We also have a number of external partners who each have their own Active Directory setups. We are trying to use Azure AD B2C to create a single location to sign on. Adding multiple identity providers is easy, but buttons show up for each provider and due to privacy concerns we can not allow our partners to know who else we partner with. We wish to ask for an email, and direct the user to the correct identity provider based on the domain of the email.
I know there are ways to do this, however all of the ones I have found so far are extremely convoluted. The requirements for this feel like they would be very common in many businesses, so the concept that the easiest ways to implement this require approximately a hundred steps doesn't seem right.
I'm aware of Home Realm Discovery, but like above all examples I see of it require immensely complex setups (custom policies with claims providers calling an azure function to query from a database to return the idP), we already have to setup the Identity Providers is there really no simple way to say "emails from parter1.com use this provider, emails from partner2.com use this one"? If not, could someone explain the lease complex way of achieving this?
See this sample which collects email and does the HRD based on domain name.
https://github.com/azure-ad-b2c/samples/tree/master/policies/home-realm-discovery-modern
You must use custom policy if you collect email in the B2C page.
If you collect email in the app, then you could use a User Flow with a domain_hint param. You don’t need to do any xml work, just pass a domain_hint parameter equal to the idp name in the portal.

Salesforce: How to automate report extraction as JSON/CSV

I am new to Salesforce, but am an experienced developer. I am provided a link to a Salesforce report, which mostly has the right filters (query). I would like to use an REST API to pull that information as CSV or JSON so that I can do further processing on it.
Here are my questions:
Do I need special permissions to make API calls? What are they?
Do I need to create an "app" with client-key & secret? Does my admin need to grant me permission for this too?
There are a lot of REST APIs from Salesforce, which one do I need to get the info from the report? Analytics?
How do I authenticate in code?
You'd have to work with the System Administrator on the security pieces. Anybody who knows how the company works, can all users see everything, is there Single Sign-On in place, how likely is the report to change...
You will need an user account to pull the data. You need to decide if it'll be some "system account" (you know username and password and have them stored in your app) or can it run for any user in this org. It might not matter much but reports are "fun". If there will be data visibility issues 6 months from now, you'll be asked to make sure the report shows only French data to French users etc... you can make it in report filters or have multiple reports - or you can just use current users access and then it's the sysadmin that has to set the sharing rules right. (would you ever think about packaging what you did and reusing in another SF instance? Making a mobile app out of it? Things like that, they may sound stupid now but will help you decide on best path)
The user (whether it'll be system account or human) needs Profile permissions like "API Enabled" + whatever else you'd need normally ("Run Reports" etc). If you're leaning towards doing it with system user - you might want to look at Password Policies and maybe set password to Never Expires. Now this is bit dangerous so there would be other things you might want to read up about: "API only user" (can't login to website), maybe even locking down the account so it can login only from certain IP ranges or at certain times when the job's supposed to be scheduled...
Connected App and OAUth2 stuff - it's a good idea to create one, yes. Technically you don't have to, you could use SOAP API to call login, get session id... But it's bit weak, OAuth2 would give you more control over security. If you have sandboxes - there's little-known trick. You can make connected app in production (or even totally unrelated Developer Edition) and use client id & secret from it to login to sandboxes. If you create app in sandbox and you refresh it - keys stop working.
(back to security piece - in connected app you can let any user allow/deny access or sysadmin would allow only say these 3 users to connect, "pre-authorize". Could be handy)
Login - there are few REST API ways to login. Depends on your decision. if you have 1 dedicated user you'll probably go with "web server flow". I've added example https://stackoverflow.com/a/56034159/313628 if you don't have a ready SF connection library in your programming language.
If you'll let users login with their own credentials there will be typical OAuth "dance" of going to the target page (Google login, LinkedIn, Twitter...) and back to your app on success. This even works if client has Single Sign-On enabled. Or you could let people type in their username and pass into your app but that's not a great solution.
Pull the actual report already
Once you have session id. Official way would be to use Reporting API, for example https://developer.salesforce.com/docs/atlas.en-us.api_analytics.meta/api_analytics/sforce_analytics_rest_api_get_reportdata.htm
A quick & dirty and officially not supported thing is to mimic what happens when user clicks the report export in UI. Craft a GET request with right cookie and you're golden. See https://stackoverflow.com/a/57745683/313628. No idea if this will work if you went with dedicated account and "API access only" permission.

Profile Management with Identity Server

So from what I have read on IdentityServer I should be storing details about the user such as first name and last name inside claims. How would a web application then be able to access the claim information? Since the User Info endpoint requires a valid access token representing the user, I suppose I would need to make an API that could access that returned the profile information of other users? Is this the right way to do it? (use case, web page needs to display contact details that are stored in claims of another user)
Also what would be the way for multiple language profile information be stored and retrieved in the claims? For example a user can have a name/title in multiple languages. I'm thinking of making [LanguageCode]_[ClaimType] (fr_first_name) naming convention and either adding all languages to just the profile IdentityResource or creating separate resources per language.
Your best bet is to set up a project using the IdentityServer4 QuickstartUI example and review that code to better understand how it all works. As of version 4, Identity Server is only focused on the sign-in / sign-out process and the various flows around authentication. They also provide a basic EF-driven persistence model, and they also support the ASP.NET Core Identity persistence model (also EF-driven), but both of those are not meant to be production-ready code.
Basically, persistence of user details is considered your responsibility. That being said, the cookies used for ASP.NET Core authentication greatly restricts how much data you can/should store as claims. The best model is to keep "real" identity provider (IDP) claims as claims, don't add new claims to that list, copy what you need into some other separate user-data table you manage completely, and use the unique claims identifier (almost always "subject id") as the key to your user data. This also makes it easier to migrate a user to another IDP (for example, you'll know user details for "Bob" but he can re-associate his user data away from his Facebook OIDC auth to his Google auth).
Basic persistence isn't too difficult (it's only 12 or 13 SQL statements) but it's a lot more than will fit in a Stackoverflow answer. I blogged about a non-EF approach here -- also not production-ready code (for example, it has ad-hoc SQL to keep things simple), but it should get you started.

Multiple tokens (for multiple services) for single user in mobile application

I am making a hybrid mobile application, using Ionic and Cordova, for which I would like to give the user the possibility to sign up/log in with Facebook, G+, Linkedin and Instagram, and email account. I would indentify everyone by their email (to check if it's the same person, it is not a pk in the database but just an index).
I have been looking around for information about OAuth2 and looking into the documentation for the services APIs. I have understood what I have to do in the front, but I have some questions on the whole process:
[BACK] How do I check the tokens provided by the services APIs? Let's say when a user logs in with Facebook, I get a token which is stored in the user's phone. Then, on every HTTP request, I have to attach the JWT to verify the user indentity. How do I verify it? Against what do I have to test it?
I want to be able to get information from the user's G+ account but also the user's Linkedin account (example). How do I manage this properly?
Do I just store both (or more) tokens (in local storage) and use them to authenticate? I want to do this as my app will have "friends lists", so the user will be able to log into external services and the app will get the user's friends/contact list from those apps.
As of now, I think about including an auth_method field in my database to store available authentication methods (a JSON string or something like that), and just add four fields (one for each service) default null where I would store the token created for the user.
I can show you my code but it do not think it would help as these are more of theory and not specific to a language.
Thank you for all the help!
