I think that there is sso enabled with my aem application. Hence I don't get the same pop up.
Any thoughts if sso enabled, how we can enforce the user to login again or refresh the page to sync with Identity provider(SSO enabled) just as we reach session expiration.
1. Here you could see I have created 3 users in LDAP apache directory studio -

2. I have synchronized these apache DS users and imported to AEM -


3. I have captured all these information in ldap.log file (configured in AEM) , even authentication part also -

4. You could see I have logged in as "debalarchitect" -

5. Finally getting logged out and requested to login again if the session remains inactive for 30 mins -

Hope this will help. I have integrated AEM 6.5.9 with Apache Directory Studio 2.0.0-M14
