Auth - vse

OAuth2, OpenID Connect (OIDC), SAML -------------------------- OAuth 2.0 is a framework that controls authorization to a protected resource such as an application or a set of files, while OpenID Connect and SAML are both industry standards for federated authentication.

OpenID Connect is built on the OAuth 2.0 protocol and uses an additional JSON Web Token (JWT), called an ID token, to standardize areas that OAuth 2.0 leaves up to choice, such as scopes and endpoint discovery. It is specifically focused on user authentication and is widely used to enable user logins on consumer websites and mobile apps.

SAML is independent of OAuth, relying on an exchange of messages to authenticate in XML SAML format, as opposed to JWT. It is more commonly used to help enterprise users sign in to multiple applications using a single login.

OAuth - obecný framework na prava (authorizace), OpenID implementace nad ním pro authentikace (poda ten token), SAML mimo, FIDO novinka

OpenID Connect (OIDC) is an authentication layer on top of OAuth 2.0, an authorization framework.

Oauth (code flow - frontend + backend, implicit flow - jen frontend js)

Authentication - KDO Authorization - CO

IdentityServer is an open-source authentication server that implements OpenID Connect (OIDC) and OAuth 2.0 standards for ASP.NET Core

Active Directory is a database based system that provides authentication, directory, policy, and other services in a Windows environment

LDAP (Lightweight Directory Access Protocol) is an application protocol for querying and modifying items in directory service providers like Active Directory, which supports a form of LDAP.

Short answer: AD is a directory services database, and LDAP is one of the protocols you can use to talk to it.

Lightweight Directory Access Protocol or LDAP, is a standards based specification for interacting with directory data. Directory Services can implement support of LDAP to provide interoperability among 3rd party applications.

Active Directory is Microsoft's implementation of a directory service that, among other protocols, supports LDAP to query it's data.

Kerberos is a network authentication protocol. It is designed to provide strong authentication for client/server applications by using secret-key cryptography. Clients authenticate to Active Directory using the Kerberos protocol.

AD je ta db, kerberos je protokol (kerberos vs openid jde porovnat - obe protokoly) Azure Active directory - je ta db v azure, včetne services, je to identity provider - umi pres openid snad Identity server je framework co pouziju pro napsani serveru, ale nema to tu spravu dat co ma AD a ui, to si musim poskladat

---- Oauth flow Implicit - uz nedoporucovana, jen ciste spa The application opens a browser to send the user to the OAuth server The user sees the authorization prompt and approves the app’s request The user is redirected back to the application with an access token in the URL fragment *****

Code flow The application opens a browser to send the user to the OAuth server The user sees the authorization prompt and approves the app’s request The user is redirected back to the application with an authorization code in the query string ****** The application exchanges the authorization code for an access token ******

Configure IdentityServer for Xamarin Forms

In this new post, I explain how to configure IdentityServer for Xamarin Forms to integrate Web Authenticator using Xamarin Essentials.

First, I wrote a post about how to implement the authentication in Xamarin Forms with IdentityServer. So, my focus was only on the Xamarin side. Here I want to explain what the IdentityServer configuration is in order to succeed in the login.

Create a new client

Have you ever wondered how hard it would be to set up a minimal viable authentication server that uses industry standards and usable from your mobile Xamarin application? Well, I have, and I believe in having found a solution that can be a great starting point and will allow you to expand the answer should you ever need to do so.

One common industry standard is OpenID / OAuth2, which provides a standardized authentication mechanism that allows user identification securely and reliably. You can think of the identity service as a web server that identifies a user and provides the client (website/mobile app, etc.) to authenticate itself with another application server that said client uses.

The recommended flow for a mobile app

While the OAuth standard is open to anyone with a computer and an internet connection, I generally do not recommend writing your own implementation. My go-to solution for setting up an identity provider is the IdentityServer.

IdentityServer4 is built based on the OAuth spec. It is built on the trusted ASP.NET Core but requires quite some know-how to get the configurations and other settings ready for use. Luckily, there is a quickstart template that you can install via the dotnet command line and then make your server. You can find the repository here on GitHub. After following the install instructions, we can create a server with the following command:

dotnet new sts -n XamarinIdentity.Auth

The solution is pretty much ready to go but let’s look at the configuration of the IdentityServer in Config.cs and make some adjustments in the GetClients method.

Add a client

Based on the template, let’s make some changes that leave us with the following final configuration:

public static IEnumerable<Client> GetClients(IConfigurationSection stsConfig) { return new List<Client> { // mobile client new Client { ClientName = "mobileclient-name-shown-in-logs", ClientId = "the-mobileclient-id-of-your-choice", AllowedGrantTypes = GrantTypes.Code, AllowOfflineAccess = true, // allow refresh tokens RequireClientSecret = false, RedirectUris = new List<string> { "oidcxamarin101:/authorized" }, PostLogoutRedirectUris = new List<string> { "oidcxamarin101:/unauthorized", }, AllowedScopes = new List<string> { "openid", "role", "profile", "email" } } }; }

Generally, you can set the ClientName, ClientId, RedirectUris and PostLogoutRedirectUris to values of your choosing. The scopes represent the defaults. Further note that by setting AllowOfflineAccess to true, the user can request refresh tokens which means that as long as the refresh token is valid, the user will not have to log in but can use said refresh token to request a new access token. In mobile apps, this is generally the prefered behaviour since users usually have their personal device and therefore expect the app to “store” their login.

As you can see, The RedirectUris and PostLogoutRedirectUris are using a custom URL oidcxamarin101:/ that identifies my app.

IdentityServer Admin

So, very often we have to create the front-end to manage users, integrate the authentication with external services suck as Facebook and Twitter, make API calls secure. IdentityServer offers a nice UI for administration but it is quite expensive. Now, I found a very nice work on GitHub: Skoruba.IdentityServer4.Admin.

This is cool! The application is written in ASP.NET Core MVC using .NET5.

Skoruba IdentityServer4 Admin UI

Add a new client

So, adding a new client with this UI is quite easy. In the IdentityServer Admin website, create a new Client. Then, the important configuration are:

Under Basic

Add this RedirectUris : oidcxamarin101:/authenticated

Allowed Grant Types: authorization_code

Under Authenticaton/Logout

Add Post Logout Redirect Uris: oidcxamarin101:/signout-callback-oidc

Basic configuration

Authentication/Logout configuration

I hope this is useful! Do you know Microsoft is releasing .NET MAUI that will replace Xamarin? Here how to test it with Visual Studio 2022.

If you have any questions, please use the Forum. Happy coding!
