cookie-path

I've got two grails applications using spring security: Core Module (user and role tables mapping to Core db tables) I want to have a single sign on functionality using "remember me". The problem is that the cookies are stored in different paths "/Core" and "/Module" which I'm guessing is the reason why it isn't working. Does anyone know how to change the cookie path to be "/"? Notes : Do I need to make a change in Spring Security or the Tomcat server configuration (using intellij) I want to avoid setting up a CAS server if possible I'm looking into plugins as an alternative Thanks any help
