I'm working on a web application that has a (end user) user interface built in Flex and a management user interface built using Spring MVC. I'm trying to secure both interfaces and can get each one working separately, but not together.

I'm using a snapshot build of spring-flex-core 1.5.0 with Spring Security 3.1RC1 and Spring 3.1M1

Code:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

	<!-- All Spring Security related configuration goes here -->

	<security:global-method-security secured-annotations="enabled" jsr250-annotations="enabled"/>
    
    <security:http pattern="/messagebroker/**" entry-point-ref="entryPoint">
        <security:anonymous enabled="false"/>
    </security:http>
    
    <bean id="entryPoint" class="org.springframework.flex.security3.FlexAuthenticationEntryPoint"/>
     
    <security:http pattern="/favicon.ico" security="none"/>
    <security:http pattern="/login*" security="none"/>
    <security:http pattern="/logoutSuccess*" security="none"/>
    <security:http pattern="/apollo/css/**" security="none"/>
    <security:http pattern="/apollo/js/**" security="none"/>

    <security:http pattern="/MoneyManager.swf" security="none"/>
    <security:http pattern="/assets/**" security="none"/>
    <security:http pattern="/index.jsp" security="none"/>
    
    <security:http servlet-api-provision="true">

        <security:intercept-url pattern="/cms/*" access="ROLE_ADMIN"/>
        <security:intercept-url pattern="/cms/users/*" access="ROLE_ADMIN,ROLE_USER_MANAGER"/>
        <security:intercept-url pattern="/cms/content/*" access="ROLE_ADMIN,ROLE_CONTENT_MANAGER"/>        
        <security:intercept-url pattern="/**" access="ROLE_USER,ROLE_ADMIN" />

        <security:form-login login-page="/login.html" default-target-url="/home.html" 
        					always-use-default-target="false" authentication-failure-url="/login.html"/>
        					
        <security:remember-me/>
        <security:logout logout-url="/logout" logout-success-url="/default.html" />
		
    </security:http>
    
    <bean id="successfulLogInListener" class="uk.co.ecube.web.security.SuccessfulLogInListener"/>
    <bean id="failedLogInListener" class="uk.co.ecube.web.security.FailedLogInListener"/>
    

	<security:authentication-manager>
    	<security:authentication-provider user-service-ref='userService'/>
  	</security:authentication-manager>
</beans>

If I include only the first http tag without the pattern attribute then the flex UI appears to authenticate successfully using Spring security. However if I include all the [CODE] http tags then I get one of two errors depending on whether I use

Code:
    <security:http  entry-point-ref="entryPoint">
        <security:anonymous enabled="false"/>
    </security:http>
which gives
Code:
SEVERE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: The filter chain map already contains this request matcher [Root bean: class [org.springframework.security.web.util.AnyRequestMatcher]; scope=; abstract=false; lazyInit=false; autowireMode=0; dependencyCheck=0; autowireCandidate=true; primary=false; factoryBeanName=null; factoryMethodName=null; initMethodName=null; destroyMethodName=null]. If you are using multiple <http> namespace elements, you must use a 'pattern' attribute to define the request patterns to which they apply.
or

Code:
    <security:http pattern="/messagebroker/**" entry-point-ref="entryPoint">
        <security:anonymous enabled="false"/>
    </security:http>
which results in

Code:
SEVERE: Servlet /apollo threw load() exception
org.springframework.beans.factory.NoSuchBeanDefinitionException: No unique bean of type [org.springframework.security.web.authentication.session.SessionAuthenticationStrategy] is defined: expected single matching bean but found 2: [org.springframework.security.web.authentication.session.SessionFixationProtectionStrategy#0, org.springframework.security.web.authentication.session.SessionFixationProtectionStrategy#1]
	at org.springframework.beans.factory.support.DefaultListableBeanFactory.doResolveDependency(DefaultListableBeanFactory.java:796)
I'm obviously missing something but while the Spring Flex documentation describes how to configure a hybrid MVC+Flex application at the servlet level it appears to only consider security from the perspective of a flex-only application.

Can anyone suggest what I'm doing wrong?

thanks
