How to protect Spring MVC + Flex hybrid application with Spring Security

I tried asking for it in the Spring forums ( http://forum.springsource.org/showthread.php?109948-Problem-configuring-spring-security-3.1-with-hybrid-Spring-MVC-Flex-application ), but not received an answer.

I am working on a web application that has a user interface (end user) built into Flex, and a management user interface built using Spring MVC. I am trying to protect both interfaces and I can get each of them working separately, but not together.

I am using spring-flex-core 1.5.0 snapshot assembly with Spring Security 3.1RC1 and Spring 3.1M1
