Reopen the ticket because closed without fix. Extract of OpenID Connect standard (http://openid.net/specs/openid-connect-core-1_0.htm), §5.3.2 : "The sub (subject) Claim MUST always be returned in the UserInfo Response." With Gluu 2.2.0, only a field named "inum" is returned with the concerned data. With Gluu 1.7.0, the field was named "sub" so it was correct. Why its name is now "inum" ? This is not compatible with OpendId connected definition. The problem still exists in 2.3 version. When will it be fixed ?
