Configuring OAuth2-OpenID Connect¶
OAuth 2.0 is an authorization framework that is capable of providing a way for clients to access a resource with restricted access on behalf of the resource owner. OAuth 2.0 is capable of authorizing the flows for web applications, desktop applications, and mobile applications among others.
OpenID Connect is an authentication protocol built on top of OAuth 2.0, which facilitates clients to verify the end-user identity against the authentication performed by an authorization server. At the same time, it provides methods to transfer the end user information through claims.
Sign in. Enter your username and password to log on to the Management Console.
Navigate to the Main menu to access the Identity menu. Click Add under Identity Providers.
For more information, see Adding and Configuring an Identity Provider.
Fill in the details in the Basic Information section.
Expand the Federated Authenticators section and then the OAuth2/OpenID Connect Configuration form.
WSO2 Identity Server supports RP-initiated logout requests to OpenID Connect identity providers.
To use this feature, apply the 0147 WUM update for WSO2 Identity Server 5.9.0 using the WSO2 Update Manager (WUM). To deploy a WUM update into production, you need to have a paid subscription. If you do not have a paid subscription, you can use this feature with the next version of WSO2 Identity Server when it is released. For more information on updating WSO2 Identity Server using WUM, see Getting Started with WUM.
Fill in the following fields where relevant.
Prior to this, you need to configure an oauth application in the federated authorization server and get the application information such as client ID and secret. For example, see configuring OAuth2-OpenID Connect single sign-on.
By default, the Client Id and Client Secret are stored as plain text values, where the Client Secret is generally stored as a random number generated using two UUIDs and HMAC-SHA1 hash function, which is known to resist the strongest attack known against HMAC.
If you want to change the format in which the Client Secret is stored, open the
<IS_HOME>/repository/conf/deployment.tomlfile and add the following configuration.
For information on possible values that you can specify based on your requirement, see Supported token persistence processors.
[oauth] hash_tokens_and_secrets = true
Once you configure a required token persistence processor, be sure to restart the server for the changes to be applied to WSO2 Identity Server.
Field Description Sample value Enable OAuth2/OpenIDConnect Selecting this option enables OAuth2/OpenID Connect to be used as an authenticator for users provisioned to the Identity Server. Selected Default Selecting the Default check box signifies that the OAuth2/OpenID Connect credentials are the main/default form of authentication. This removes the selection made for any other Default checkboxes for other authenticators. Selected Authorization Endpoint URL This is a standard OAuth Authorization Endpoint URL of the federated IDP. https://localhost:9443/oauth2/authorize/ Token Endpoint URL This is a standard OAuth Token Endpoint URL of the federated IDP. https://localhost:9443/oauth2/token/ Client Id Client ID of the application you registered in the IDP for Identity server. 1421263438188909 Client Secret Client Secret of the application you registered in the IDP for Identity server. Click the Show button to view the value you enter. 12ffb4dfb2fed67a00846b42126991f8 Callback URL This is the URL to which the browser should be redirected after the authentication is successful. It should be the commonauth endpoint of Identity server https://localhost:9443/commonauth Userinfo Endpoint URL This is the URL of the federated identity provider's userinfo URL https://localhost:9443/oauth/userinfo OpenID Connect User ID Location Select whether the User ID is found in the 'sub' attribute that is sent with the OpenID Connect request or if it is found among claims. User ID found in 'sub' attribute Additional Query Parameters This is necessary if you are connecting to another Identity Server or application. Sometimes extra parameters are required by this IS or application so these can be specified here. paramName1=value1 Enable HTTP basic auth for Selecting this option enables HTTP basic authentication to be used for client authentication, else client credentials will be included in the request body Selected client authentication
