We are currently running EE 2.5.2 and using the Discussion Forum Module (3.1.8). We have several users who report that they are logged out even when they have checked the 'keep logged in' option. We've triple checked our cookie settings and verified the cookie domain is correct and that the 'keep logged in' option has a cookie with an expiration date set to a year from the log in date. Our user sessions are currently at the default 2 hours, so we are NOT using the 'user_session_ttl' hidden variable. We also have the User Session Type set to 'Cookies Only' in the 'Security and Session Preferences', so I assume any of the session stuff shouldn't matter. All of our cookies to set to the full domain 'www.macobserver.com' and I have not yet tried setting the cookie domain setting in EE as it doesn't seem like we should have to.
My questions are: 1) Are there know issues with cookie logins and the Discussion Forum Module?
2) Should I set the Cookie domain setting anyway even though it's seems like it should be required?
