Description

Standard Token Endpoint response has only access token lifetime. It does not have refresh token lifetime.

We need to introduce new AS configuration property which will force AS to return refresh token lifetime in token reponse. JSON key "refresh_token_expires_in".

Example

{
  "access_token": "...",
  "refresh_token": "...",
  "scope": "openid user_name offline_access profile email",
  "id_token": "...",
  "token_type": "Bearer",
  "expires_in": 299,
  "refresh_token_expires_in": 1399                   <-- new non-standard field
}
