I deployed wso2 IS 5.3.0 in docker. I set it up for openid connect authentication. I tried to have kubernetes to work with it for authentication. But it turns out to have problem with iss field in idtoken. The payload part of the token looks like below after decode:

{"exp":1487335376,"sub":"admin","azp":"Dibo_uMHzySCIxrf55uvMGWjGEUa","at_hash":"_8q5TmtJRsdEj4V_dL4-Zg","aud":["Dibo_uMHzySCIxrf55uvMGWjGEUa"],"iss":"https:\/\/localhost:9443\/oauth2\/token","iat":1487331776,"acr":"urn:mace:incommon:iap:silver"} 

By openid connect spec, the iss field is expected to be "https://192.168.1.123:9443/oauth2/oidcdiscovery/" in my case. How can I do to change the iss value of default in idtoken?

Thanks
