Force logout in autologin hook/portlet

[Helmut Steiner, modificado hace 8 años.]

Liferay does not log the currently logged in user if you try to login again, and in fact even keeps the currently logged in user logged in.

For that i wanted to do it programmatically.

I tried it this way but with no success:

request.getSession().invalidate();

I was wondering if anyone has any other idea how to force a logout.

Thanks a lot.

Hello Helmut Steiner,
Thanks for posting.

Note this issue has been addressed before:

To quote from the author from answer post:

David O Meara:

session.invalidate() only works if authentication is managed by the application server session, which it is not ;)

So it's worth asking what is the "Auto"? Is this a custom Auto Login class? Or is it some cookie-based login class? If it's cookie based, clear the cookies?
