Hello I wrote a JPA federation provider which works perfectly but I'm not able to add claims via the client mappers table. For example, I have a User property "gender" which is mapped to my UserModel getGender method, which does mapping to the underline hibernate entity. I configured the mapper as: Consent required: Off Mapper Type: user Property Property: gender Token Claim Name: person_gender Clain JSON Type: string Add ID token: ON Add to Access Token: ON Add to userinfo: ON While the hibernate entity correctly loads the value, the claim is never included in the userinfo object. To develop the provider I basically followed the user-storage-jpa example. Server version is 3.4.0.Final Best regards Francesco
