George Angeletos (Migrated from SEC-2692) said:

By default in Tomcat 7 the session fixation protection is enabled. That means that if you are using SSL mutual (client-cert) authentication (Tomcat side) and form-login authentication with SS the concurrency control is effectively bypassed.

In order for the CompositeSessionAuthenticationStrategy to properly work the changeSessionIdOnAuthentication attribute must be set to false on the SSLAuthenticator in /conf/context.xml:

<Valve className="org.apache.catalina.authenticator.SSLAuthenticator" changeSessionIdOnAuthentication="false" />

Please add a warning in the documentation ( as it's a big frustration - at least it was for me :)
