OK, I set Pre-Authorization=Disable, but nothing is changed.
Causes https://gluu/oxauth/seam/resource/restv1/oxauth/authorize?client_id=<CLIENT_ID>&redirect_uri=<REDIRECT_TO_LOGIN_PAGE>&response_type=code&scope=openid%20profile&state=CiRFMD', then I have a login page (user, password) , and then displays a page of my redirect_uri.
I tried to set a parameter prompt = consent , but also does not help.
