CAS с Spring Security — цикл перенаправления

Я настраивал решение SSO с помощью CAS для существующего приложения с интегрированной Spring Security. Я прочитал много ответов на Stackoverflow, но, к сожалению, любой мог мне помочь. Не могли бы вы помочь мне с этой проблемой с точки зрения моей конфигурации? Заранее спасибо!

Вот моя основная конфигурация безопасности:

<!-- Responsible for propagation of SecurityContext on ThreadLocal from HttpSession -->

<bean class="org.springframework.security.web.access.DefaultWebInvocationPrivilegeEvaluator">

And also we have separate module web-security-urls.xml where o.s.s.web.access.intercept.FilterSecurityInterceptor is configured to declare secure URLs
