Apache Ignite Spring secutiry error

I'm trying to develop an application with spring security login functionality while user session is distributed using apache Ignite.

Server: Apache Tomcat 8
Spring version: 4.2.2.RELEASE
Ignite version: 2.1.0

I have two errors in my application.

Logging an exception when logging out from the application. Apart from that session invalidation is done as expected.

When two tomcat servers with same application deployments started up in two different ports, can access login page only from one server. (If I accessed login page from first server page is loaded fine as expected. But if I tried to access login page from second server again it gives error. However once logged in application worked as expected and could access distributed session from both servers.
1. First access

Second access from another server

My configuration files are as follows.

I would be very thankful if you could provide any solution / idea to solve problem.

Solution

As both of your deployments are on localhost, they're going to share JSESSIONID cookie. So far so good.

However there seems to be a mismatch between Tomcat, Spring Security and Ignite which causes Spring Security to regard sessions coming from Ignite as invalid when they're anonymous (i.e. not logged on). I don't understand yet how this relates to your case where you're supposed to already be logged on.

You can probably use a workaround: Remove invalid-session-url="/" from your Spring Security configuration. This will prevent the redirect looping behavior. This will also cause users to be silently logged off instead to being guided to /login when their cookie expires.

I've deleted my previous answer as it was missing the point.
