Issue with portal 7.3 log off

Hi All,

We are facing issues with SAP portal 7.3 log off . 

Scenario : User A is logged in and logs out after sometime ,which works fine. User B logs in same session but it still shows same user ID(UserA) . However ,this issue doesn’t occur for second log out.

Kindly suggest if anything needs to be configured specifically.

Thank you!

Regards
