[keycloak-user] KEYCLOAK_SESSION cookie not getting set in Keycloak 4.1.0. Was getting set in Keycloak 3.4.3

Wed Aug 1 00:31:04 EDT 2018

In keycloak 3,4.3:
First time I run the app,  AUTH_SESSION_ID,  KEYCLOAK_IDENTITY,
KEYCLOAK_SESSION cookies are set and next time I run the app (before
session idle timeout), I do not have to relogin as session cookie has a
valid session.

In keycloak 4.1.0 ,
First time I run the app and login: AUTH_SESSION_ID cookie is set. Next
time I run the app, KC_RESTART cookie gets set and I am presented the login
form again. My assumption is KC_RESTART cookie gets set because there is no
valid  KEYCLOAK_SESSION cookie. Am I right?

How can I resolve this issue? I am sure there is some config I have missed.
