Login App with IdentityServer4 RRS feed

  • Question

  • Hello everyone!

    I have to develop a SSO system and I have to do it using IdentityServer4. I have gone through the documentation and examples but I have some doubts. To be honest I don't quite get it, but I am really new in Oauth2 and OpenId Connect.

    We will have a bunch of clients (web apps), each of one of those will have their own Web APi. And we have to have a centraliced Login App for all of those. I think the example with the javascript client is the closes to the thing we want to achieve. Also, a user might have permission to access one client (app), but not another, so the IdentityServer must provide information about wich clients (apps), that particularly user can access.

    So, These are the things I don Understand:

    1.- In the documentation I can read there are two tokens, an Identity Token and Access token. But in the examples all I see are the access tokens. It seems to me that the access token is the one with all de info needed. am I wrong?

    2.- Also, I have read about de Grant Types and I'am not quite sure wich one we must use. At first I thought to use the ResourceOwner password, because it requires the client, the secret, a user and a password, wich I assumed it could be the end user. I found one example  were one could customise the class that validate the user and password. I thought that this could be the way to go but the documentation statesa about this grant type "...This is so called “non-interactive” authentication and is generally not recommended.". The javascript client example uses the implicit Grat type, wich the documentation states is for browser-based applications (our client apps will all be browser based using react).

    3.- can my Login app be a Javascript (react) app? The example Quickstart is made in MVC.NET. This login app connects directly to de IS4 server without asking for a access token? (In the example the app is embebed in the IS4).

    4.- Can I protect with IS4 a WEB API which is developed in .net framework (4.6.2) and not in .Net Core? I havent Found Any examples.

    the documentatios I followed is the offcial. The examples (quickstart) are also there. (I can't post more than two links).

    thank you very much for reading and for your help.
