We have integrated our application to ONAP Beijing SDK and it is onoboarded into ONAP portal as well.

 Our application gets the logged in user in portal and we use the below method to do so

UserUtils.getUserSession(request); which exists in     package org.onap.portalsdk.core.domain.User;

While testing login/logout functionalities, The login feature is working properly but there is an issue with logout feature as per the below scenario

1- User logs into the portal

2- Our application can get the logged in user correctly

3- When user try to log out from the portal, he can log out successfully

4- If another user try to login to the portal using the same browser, our application reads the same previous logged in user. It seems that the session still see the previous logged in user and it is not updated with the new logged in user 

5- We tried to figure out the problem through logs files, but we found that the logs file are empty.

Please advise
