[keycloak-user] No ID token in headers OpenID connect, apache OIDC

Hi all, Sorry for the newbie question. I have keycloak set up and the apache OIDC adapter protecting a php website. However, when I look at the headers after login (using the OIDCResponseType code) , I am only seeing the access token and no ID token. Is there a setting I am missing in the keycloak configuration? Thanks!
