In this post I am going to talk about overall global logout implementation.<\/font>\u00a0<\/font><\/strong><\/p>\n

Problem description:<\/strong><\/font>\u00a0<\/strong><\/font><\/p>\n

For Example:<\/strong><\/font><\/p>\n

1.<\/font>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Login into portal with user \u201cA\u201d. <\/font><\/p>\n

2.<\/font>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Click the app link for example “X”, and application will open in new browser with user \u201cA\u201d.<\/font><\/p>\n

3.<\/font>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Logout from portal, and login again in same session with different user \u201cB\u201d.<\/font><\/p>\n

4.<\/font>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Again click the app link but now application not opening with user \u201cB\u201d its opening with user \u201cA\u201d.<\/font>\u00a0<\/font><\/p>\n

Regarding this issue we have implemented the chain call method, its mean calling all application logout page\u2019s. This approach will helps us to clear the application cookies and sessions.<\/font>\u00a0<\/font><\/p>\n

Advantage & Disadvantage:<\/strong><\/font>\u00a0<\/font><\/p>\n

Clear the cookie and sessions, it will help us to see the new session.<\/font>\u00a0<\/font><\/p>\n

Logout can fail for any reason say any server is down, server not responding etc.<\/font>\u00a0<\/font><\/p>\n

For more information click <\/font>here<\/font><\/a>.<\/font>\u00a0<\/font>\u00a0<\/font><\/p>\n

For this problem I have come out with the below approach to overcome this issue. My approach as follow,<\/font>\u00a0<\/font><\/p>\n

1.<\/font>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Removing the chain call of logout pages.<\/font><\/p>\n

2.<\/font>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Modified in application level.<\/font>\u00a0<\/font><\/p>\n

More information about my approach here.<\/font>\u00a0<\/font><\/p>\n

Why above mentioned issues is occurring?<\/strong><\/font>\u00a0<\/strong><\/font><\/p>\n

Ans: <\/strong><\/font>\u00a0<\/font><\/p>\n

1.<\/font>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 First time login into portal with user \u201cA\u201d and then access application “X”, now in application level they are checking whether any session is exist or not if not then they read the header variable what IDM passed.<\/font><\/p>\n

2.<\/font>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 second time I\u2019m accessing the some other link in application in “X”, here again they checking any session is exist or not, here we have session of previous user so they continue with same session.<\/font><\/p>\n

3.<\/font>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 after logout from portal and login again with user \u201cB\u201d.<\/font><\/p>\n

4.<\/font>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Access the\u00a0application “X”, this time they checking whether any session is exist or not, yes previous session is not deleted, so again continue with same session.<\/font>\u00a0<\/font><\/p>\n

Note:<\/strong> problem is they are not comparing the IDM cookie, they only checking their session value.<\/font>\u00a0<\/font><\/p>\n

We made some changes in application level\u00a0to compare the application “X” session value with IDM cookie value. If it not matches then remove the old session and create the new session. Now above issue get vanished.<\/font>\u00a0<\/font><\/p>\n

Advantage:<\/strong><\/font><\/p>\n

1.<\/font>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 No Looping. No need to worry about whether all servers are up and running or not.<\/font><\/p>\n

2.<\/font>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Now portal and IDM will come into GL.<\/font><\/p>\n

3.<\/font>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 It faster than before implementation.<\/font>\u00a0<\/font><\/p>\n","protected":false},"excerpt":{"rendered":"
