wso2 identity server oauth userinfo only returns sub

Question

I have set up SP in wso2 Identity server and was able to get access_token in auth2 using playground. Ref : https://docs.wso2.com/display/IS510/OAuth+2.0+with+WSO2+Playgroun

Answer 1

It seems the logic to return claims by UserInfo Endpoint for scope openid is only the intersection of claims configure at OIDC file and claims configured in SP level are returned. Based on this logic I was able to solve this problem by following steps.

1. WSO2 IS default openid scope is bound to set of predefined claims. You can configure this using oidc file found in /_system/config/oidc as in following screenshot.
2. Say for eg. if you want to get user's email address using openId scope by default it should comes with userInfo endpoint because "email" scheme is set-up by default (see above screenshot)
3. According to default claims
   • http://wso2.org/claims - Default dialect for WSO2 Carbon
   • http://wso2.org/oidc/claim - Default dialect for OpenID Connect

Look at values of Claim Uri and Mapped Attribute of the email claim at http://wso2.org/oidc/claim dialect

4. Now you need to add correct http://wso2.org/claims claim which is mapped to the email claim in http://wso2.org/oidc/claim to the SP configuration. You can find it using same Mapped Attribute. i.e. For this example there is a same "Email" claim in http://wso2.org/claims.
5. Add "Email" claim in http://wso2.org/claims to the SP configuration

Now for the request

curl -k -H "Authorization: Bearer 8b2805a7-5b74-33ee-84df-2a8c53a16f6c" https://localhost:9443/oauth2/userinfo?schema=openid

you would get response

{"sub":"admin@carbon.super","email":"admin@wso2.com"}
