ABP OpenIddict Module

OpenIddict module provides an integration with the OpenIddict which provides advanced authentication features like single sign-on, single log-out, and API access control. This module persists applications, scopes, and other OpenIddict-related objects to the database.

How to Install

This module comes as pre-installed (as NuGet/NPM packages). You can continue to use it as a package and get updates easily, or you can include its source code into your solution (see get-source CLI command) to develop your custom module.

The Source Code

The source code of this module can be accessed here. The source code is licensed by MIT, so you can freely use and customize it.

User Interface

This module implements the domain logic and database integrations but does not provide any UI. Management UI is useful if you need to add applications and scopes on the fly. In this case, you may build the management UI yourself or consider purchasing the ABP Commercial which provides the management UI for this module.

Relations to Other Modules

This module is based on the Identity Module and has an integration package with the Account Module.

Options

OpenIddictBuilder

OpenIddictBuilder can be configured in the PreConfigureServices method of your OpenIddict module.

Example:

public override void PreConfigureServices(ServiceConfigurationContext context)
{
	PreConfigure<OpenIddictBuilder>(builder =>
	{
    	//Set options here...		
	});
}

OpenIddictBuilder contains various extension methods to configure the OpenIddict services:

  • AddServer() registers the OpenIddict token server services in the DI container. Contains OpenIddictServerBuilder configurations.
  • AddCore() registers the OpenIddict core services in the DI container. Contains OpenIddictCoreBuilder configurations.
  • AddValidation() registers the OpenIddict token validation services in the DI container. Contains OpenIddictValidationBuilder configurations.

OpenIddictCoreBuilder

OpenIddictCoreBuilder contains extension methods to configure the OpenIddict core services.

Example:

public override void PreConfigureServices(ServiceConfigurationContext context)
{
	PreConfigure<OpenIddictCoreBuilder>(builder =>
	{
    	//Set options here...		
	});
}

These services contain:

  • Adding ApplicationStore, AuthorizationStore, ScopeStore, TokenStore.
  • Replacing ApplicationManager, AuthorizationManager, ScopeManager, TokenManager.
  • Replacing ApplicationStoreResolver, AuthorizationStoreResolver, ScopeStoreResolver, TokenStoreResolver.
  • Setting DefaultApplicationEntity, DefaultAuthorizationEntity, DefaultScopeEntity, DefaultTokenEntity.

OpenIddictServerBuilder

OpenIddictServerBuilder contains extension methods to configure OpenIddict server services.

Example:

public override void PreConfigureServices(ServiceConfigurationContext context)
{
	PreConfigure<OpenIddictServerBuilder>(builder =>
	{
    	//Set options here...		
	});
}

These services contain:

  • Registering claims, scopes.
  • Setting the Issuer URI that is used as the base address for the endpoint URIs returned from the discovery endpoint.
  • Adding development signing keys, encryption/signing keys, credentials, and certificates.
  • Adding/removing event handlers.
  • Enabling/disabling grant types.
  • Setting authentication server endpoint URIs.

OpenIddictValidationBuilder

OpenIddictValidationBuilder contains extension methods to configure OpenIddict validation services.

Example:

public override void PreConfigureServices(ServiceConfigurationContext context)
{
	PreConfigure<OpenIddictValidationBuilder>(builder =>
	{
    	//Set options here...		
	});
}

These services contain:

  • AddAudiences() for resource servers.
  • SetIssuer() URI that is used to determine the actual location of the OAuth 2.0/OpenID Connect configuration document when using provider discovery.
  • SetConfiguration() to configure OpenIdConnectConfiguration.
  • UseIntrospection() to use introspection instead of local/direct validation.
  • Adding encryption key, credentials, and certificates.
  • Adding/removing event handlers.
  • SetClientId() to set the client identifier client_id when communicating with the remote authorization server (e.g for introspection).
  • SetClientSecret() to set the identifier client_secret when communicating with the remote authorization server (e.g for introspection).
  • EnableAuthorizationEntryValidation() to enable authorization validation to ensure the access token is still valid by making a database call for each API request. Note: This may have a negative impact on performance and can only be used with an OpenIddict-based authorization server.
  • EnableTokenEntryValidation() to enable authorization validation to ensure the access token is still valid by making a database call for each API request. Note: This may have a negative impact on performance and it is required when the OpenIddict server is configured to use reference tokens.
  • UseLocalServer() to register the OpenIddict validation/server integration services.
  • UseAspNetCore() to register the OpenIddict validation services for ASP.NET Core in the DI container.

Database Providers

Common

Table/Collection Prefix & Schema

All tables/collections use the OpenIddict prefix by default. Set static properties on the AbpOpenIddictDbProperties class if you need to change the table prefix or set a schema name (if supported by your database provider).

Connection String

This module uses AbpOpenIddict for the connection string name. If you don't define a connection string with this name, it fallbacks to the Default connection string.

See the connection strings documentation for details.

Entity Framework Core

Tables
  • OpenIddictApplications
  • OpenIddictAuthorizations
  • OpenIddictScopes
  • OpenIddictTokens

MongoDB

Collections
  • OpenIddictApplications
  • OpenIddictAuthorizations
  • OpenIddictScopes
  • OpenIddictTokens

ASP.NET Core Module

This module integrates ASP NET Core, with built-in MVC controllers for four protocols. It uses OpenIddict's Pass-through mode.

AuthorizeController -> connect/authorize
TokenController     -> connect/token
LogoutController    -> connect/logout
UserInfoController  -> connect/userinfo

Device flow implementation will be done in the commercial module.

AbpOpenIddictAspNetCoreOptions

AbpOpenIddictAspNetCoreOptions can be configured in the PreConfigureServices method of your OpenIddict module.

Example:

PreConfigure<AbpOpenIddictAspNetCoreOptions>(options =>
{
    //Set options here...
});

AbpOpenIddictAspNetCoreOptions properties:

  • UpdateAbpClaimTypes(default: true): Updates AbpClaimTypes to be compatible with the Openiddict claims.
  • AddDevelopmentEncryptionAndSigningCertificate(default: true): Registers (and generates if necessary) a user-specific development encryption/development signing certificate. This is a certificate used for signing and encrypting the tokens and for development environment only. You must set it to false for non-development environments.

AddDevelopmentEncryptionAndSigningCertificate cannot be used in applications deployed on IIS or Azure App Service: trying to use them on IIS or Azure App Service will result in an exception being thrown at runtime (unless the application pool is configured to load a user profile). To avoid that, consider creating self-signed certificates and storing them in the X.509 certificates store of the host machine(s). Please refer to: https://documentation.openiddict.com/configuration/encryption-and-signing-credentials.html#registering-a-development-certificate

Automatically Removing Orphaned Tokens/Authorizations

The background task that automatically removes orphaned tokens/authorizations. This can be configured by TokenCleanupOptions to manage it.

TokenCleanupOptions can be configured in the ConfigureServices method of your OpenIddict module.

Example:

Configure<TokenCleanupOptions>(options =>
{
    //Set options here...	
});

TokenCleanupOptions properties:

  • IsCleanupEnabled (default: true): Enable/disable token clean up.
  • CleanupPeriod (default: 3,600,000 ms): Setting clean up period.
  • DisableAuthorizationPruning: Setting a boolean indicating whether authorizations pruning should be disabled.
  • DisableTokenPruning: Setting a boolean indicating whether token pruning should be disabled.
  • MinimumAuthorizationLifespan (default: 14 days): Setting the minimum lifespan authorizations must have to be pruned. Cannot be less than 10 minutes.
  • MinimumTokenLifespan (default: 14 days): Setting the minimum lifespan tokens must have to be pruned. Cannot be less than 10 minutes.

Updating Claims In Access_token and Id_token

Claims Principal Factory can be used to add/remove claims to the ClaimsPrincipal.

The AbpDefaultOpenIddictClaimsPrincipalHandler service will add Name, Email, and Role types of Claims to access_token and id_token, other claims are only added to access_token by default, and remove the SecurityStampClaimType secret claim of Identity.

Create a service that inherits from IAbpOpenIddictClaimsPrincipalHandler and add it to DI to fully control the destinations of claims.

public class MyClaimDestinationsHandler : IAbpOpenIddictClaimsPrincipalHandler, ITransientDependency
{
    public virtual Task HandleAsync(AbpOpenIddictClaimsPrincipalHandlerContext context)
    {
        foreach (var claim in context.Principal.Claims)
        {
            if (claim.Type == MyClaims.MyClaimsType)
            {
                claim.SetDestinations(OpenIddictConstants.Destinations.AccessToken, OpenIddictConstants.Destinations.IdentityToken);
            }
	    
	    if (claim.Type == MyClaims.MyClaimsType2)
            {
                claim.SetDestinations(OpenIddictConstants.Destinations.AccessToken);
            }
        }

        return Task.CompletedTask;
    }
}

Configure<AbpOpenIddictClaimsPrincipalOptions>(options =>
{
    options.ClaimsPrincipalHandlers.Add<MyClaimDestinationsHandler>();
});

For detailed information, please refer to: OpenIddict claim destinations

Disable AccessToken Encryption

ABP disables the access token encryption by default for compatibility, it can be enabled manually if needed.

public override void PreConfigureServices(ServiceConfigurationContext context)
{
    PreConfigure<OpenIddictServerBuilder>(builder =>
    {
        builder.Configure(options => options.DisableAccessTokenEncryption = false);
    });
}

https://documentation.openiddict.com/configuration/token-formats.html#disabling-jwt-access-token-encryption

Request/Response Process

The OpenIddict.Server.AspNetCore adds an authentication scheme(Name: OpenIddict.Server.AspNetCore, handler: OpenIddictServerAspNetCoreHandler) and implements the IAuthenticationRequestHandler interface.

It will be executed first in AuthenticationMiddleware and can short-circuit the current request. Otherwise, DefaultAuthenticateScheme will be called and continue to execute the pipeline.

OpenIddictServerAspNetCoreHandler will call various built-in handlers (handling requests and responses), And the handler will process according to the context or skip logic that has nothing to do with it.

Example of a token request:

POST /connect/token HTTP/1.1
Content-Type: application/x-www-form-urlencoded

    grant_type=password&
    client_id=AbpApp&
    client_secret=1q2w3e*&
    username=admin&
    password=1q2w3E*&
    scope=AbpAPI offline_access

This request will be processed by various handlers. They will confirm the endpoint type of the request, check HTTP/HTTPS, verify that the request parameters (client. scope, etc) are valid and exist in the database, etc. Various protocol checks. And build a OpenIddictRequest object, If there are any errors, the response content may be set and directly short-circuit the current request.

If everything is ok, the request will go to our processing controller(eg TokenController), we can get an OpenIddictRequest from the HTTP request at this time. The rest will be based on this object.

Check the username and password in the request. If it is correct create a ClaimsPrincipal object and return a SignInResult, which uses the OpenIddict.Validation.AspNetCore authentication scheme name, will calls OpenIddictServerAspNetCoreHandler for processing.

OpenIddictServerAspNetCoreHandler do some checks to generate json and replace the http response content.

The ForbidResult ChallengeResult are all the above types of processing.

If you need to customize OpenIddict, you need to replace/delete/add new handlers and make it execute in the correct order.

Setting Tokens Lifetime

Update PreConfigureServices method of AuthServerModule (or HttpApiHostModule if you don't have tiered/separate-authserver) file:

PreConfigure<OpenIddictServerBuilder>(builder =>
{
    builder.SetAuthorizationCodeLifetime(TimeSpan.FromMinutes(30));
    builder.SetAccessTokenLifetime(TimeSpan.FromMinutes(30));
    builder.SetIdentityTokenLifetime(TimeSpan.FromMinutes(30));
    builder.SetRefreshTokenLifetime(TimeSpan.FromDays(14));
});

Refresh Token

To use refresh token, it must be supported by OpenIddictServer and the refresh_token must be requested by the application.

Note: Angular application is already configured to use refresh_token.

Configuring OpenIddictServer

Update the OpenIddictDataSeedContributor, add OpenIddictConstants.GrantTypes.RefreshToken to grant types in CreateApplicationAsync method:

await CreateApplicationAsync(
    ...
    grantTypes: new List<string> //Hybrid flow
    {
        OpenIddictConstants.GrantTypes.AuthorizationCode,
        OpenIddictConstants.GrantTypes.Implicit,
        OpenIddictConstants.GrantTypes.RefreshToken,
    },
    ...

Note: You need to re-create this client if you have generated the database already.

Configuring Application:

You need to request the offline_access scope to be able to receive refresh_token.

In Razor/MVC, Blazor-Server applications, add options.Scope.Add("offline_access"); to OpenIdConnect options. These application templates are using cookie authentication by default and has default cookie expire options set as:

.AddCookie("Cookies", options =>
{
    options.ExpireTimeSpan = TimeSpan.FromDays(365);
})

Cookie ExpireTimeSpan will ignore access_token expiration and expired access_token will still be valid if it is set to higher value than the refresh_token lifetime. It is recommended to keep Cookie ExpireTimeSpan and the Refresh Token lifetime same, hence the new token will be persisted in the cookie.

In Blazor wasm applications, add options.ProviderOptions.DefaultScopes.Add("offline_access"); to AddOidcAuthentication options.

In Angular applications, add offline_access to oAuthConfig scopes in environment.ts file. (Angular applications already have this configuration).

About localization

We don't localize any error messages in the OpenIddict module, Because the OAuth 2.0 specification restricts the charset you're allowed to use for the error and error_description parameters:

A.7. "error" Syntax The "error" element is defined in Sections 4.1.2.1, 4.2.2.1, 5.2, 7.2, and 8.5:

error = 1*NQSCHAR

A.8. "error_description" Syntax T he "error_description" element is defined in Sections 4.1.2.1, 4.2.2.1, 5.2, and 7.2:

error-description = 1*NQSCHAR
NQSCHAR = %x20-21 / %x23-5B / %x5D-7E

Demo projects

In the module's app directory there are six projects(including angular)

  • OpenIddict.Demo.Server: An abp application with integrated modules (has two clients and a scope).
  • OpenIddict.Demo.API: ASP NET Core API application using JwtBearer authentication.
  • OpenIddict.Demo.Client.Mvc: ASP NET Core MVC application using OpenIdConnect for authentication.
  • OpenIddict.Demo.Client.Console: Use IdentityModel to test OpenIddict's various endpoints, and call the api of OpenIddict.Demo.API.
  • OpenIddict.Demo.Client.BlazorWASM: ASP NET Core Blazor application using OidcAuthentication for authentication.
  • angular: An angular application that integrates the abp ng modules and uses oauth for authentication.

How to run?

Confirm the connection string of appsettings.json in the OpenIddict.Demo.Server project. Running the project will automatically create the database and initialize the data. After running the OpenIddict.Demo.API project, then you can run the rest of the projects to test.
