OpenID Connect Basic Client Profile¶
This topic guides you through consuming an OpenID connect basic client profile that is based on authorization code flow. The following steps outline the flow according to the OpenID specification.
- The client prepares an authentication request containing the desired request parameters.
- The client sends the request to the authorization server.
- The authorization server authenticates the end-user.
- The authorization server obtains end-user consent/authorization.
- The authorization server sends the end-user back to the client with an authorization code.
- The client requests a response using the authorization code at the token endpoint.
- The client receives a response that contains an ID token and an access token in the response body.
- The client validates the ID token and retrieves the end-user's subject identifier.
The following parameters are mandatory and have to be included in the authorization request in order to execute this flow.
|scope||Specifies the behaviour of the request.
Determines which authorization processing flow is to be used, including what parameters are returned from the endpoints used.
|client_id||The OAuth 2.0 Client Identifier valid at the authorization server.|
|redirect_uri/callback_uri||The URI which the authorization server should send the response to.|
About oidc-scope-config.xml file
oidc-scope-config.xml file enables grouping of
claims that are bound to a scope value in OpenID Connect (OIDC). By
default, the oidc-scope-config.xml file is located inside
This file can be modified to add custom scopes or claims. When the
server starts, these configurations are stored in the registry located
/oidc/ . You can customize claims or scopes from
here as well. The returned clams from id token or user info endpoint
will be decided based on both the requested scopes and requested claims.
When requesting for an OIDC token, you can specify a scope value that is
bound to a set of claims in the
file. When sending that OIDC token to the userinfo endpoint, only the
claims that are common to both the oidc-scope-config.xml and the service
provider claim configuration, will be returned.
See the Basic Client Profile with Playground topic to try out this flow with the playground sample for OAuth in WSO2 Identity Server.
