Session Invalidate not Working with LTPA-based Security

问题

I normally handle site logout with a JSP that executes <%= session.invalidate() %> then redirects to the home page. Now I am running on WebSphere authenticating using LTPA and a SSL Certificate. Session.invalidate() does not work. Someone suggested it is because WAS is using LTPA. LTPA creates an authentication cookie (LtpaToken2) that is not cleared by session.invalidate.

IBM does have a proprietary logout JSP*** I could use, but I don't want to use a vendor specific solution. Has anybody tackled a session logout that clears the LTPA cookie without being tied to a vendor's J2EE container?

回答1:

I have found solution:

• In the administrative console, click Security > Global security
• Under Custom properties, click New
• In the Name field, enter com.ibm.ws.security.web.logoutOnHTTPSessionExpire
• In the Values field, enter true
• Click Apply and Save to save the changes to your configuration
• Resynchronize and restart the server
