HI I am trying to implement Spring Security: Concurrent Session Control to limit one session at a time. I see that I only need
<http>
...
<session-management>
<concurrency-control max-sessions="1" />
</session-management>
</http>
I get this from the reference http://docs.spring.io/spring-security/site/docs/3.1.x/reference/springsecurity-single.html#ns-config . The problem that I am facing is that i get this error saying, "Configuration problem: No AuthenticationEntryPoint could be established. Please make sure you have a login mechanism configured through the namespace (such as form-login) or specify a custom AuthenticationEntryPoint with the 'entry-point-ref' attribute" I do not need to use a login page in the configuration here. I saw other posts, but I cannot find a solution to this problem. Please help me with a solution here. I will post my code below.
