Security config in parent context

[Xaer]

We have a project where the modules are layered in different contexts in a hierarchical fashion much like an "extended" version of the blog.springsource.com/2007/06/11/using-a-shared-parent-application-context-in-a-multi-war-spring-application/ strategy (add http at beginning of link).

Top level:
common-module with DB connection and transaction configuration, etc

<beans>
<bean id="commonContext" class="ClassPathXmlApplicationContext">
  <constructor-arg>
    <list>
      <value>classpath:META-INF/spring/config.xml</value>
      <value>classpath:META-INF/spring/cachemanager.xml</value>
	  <value>classpath:META-INF/spring/datasource.xml</value>
	  <value>classpath:META-INF/spring/transaction.xml</value>
    </list>
  </constructor-arg>
</bean>
</beans>

Level 2:
security-module - All Spring security related custom classes and configuration (using namespace configuration)

<beans>
<bean id="securityContext" class="ClassPathXmlApplicationContext">
  <constructor-arg>
    <list>
      <value>classpath:META-INF/spring/security-general.xml</value>
      <value>classpath:META-INF/spring/security-acl.xml</value>
    </list>
  </constructor-arg>
		
  <!-- Parent context -->
  <constructor-arg ref="commonContext" />
</bean>
</beans>

Level 3:
application1-module - This module defines all business operations and the services' methods (some of them) here have specified <sec:intercept> for method level security.

<beans>
  <bean id="businessappContext" class="ClassPathXmlApplicationContext">
    <constructor-arg>
      <list>
        <value>classpath:META-INF/spring/businessapp-config.xml</value>
        <value>classpath:META-INF/spring/businessapp-dao.xml</value>
        <value>classpath:META-INF/spring/businessapp-cache.xml</value>
        <value>classpath:META-INF/spring/businessapp-services.xml</value>
      </list>
    </constructor-arg>
		
    <!-- Parent context -->
    <constructor-arg ref="securityContext" />
  </bean>	
</beans>

Unfortunatly it wont work as the spring security automatic configuration can't find some of the needed beans, seamingly beacause the configuration was done in the parent context...?
Is there a work-around for this problem?

EDIT: I commented out the <sec:intercept>'s and then the the next problem was this when trying to log in:

2008-10-05 12:23:59,359 -  WARN [http-8080-1] [org.springframework.security.event.authentication.LoggerListener:60] - Authentication event AuthenticationFailureProviderNotFoundEvent: morten; details: org.springframework.security.ui.WebAuthenticationDetails@ffff6a82: RemoteIpAddress: 127.0.0.1; SessionId: EC29ADFB6D0F196122B9BC843DD1E030; exception: No AuthenticationProvider found for org.springframework.security.providers.UsernamePasswordAuthenticationToken

yet again this is beacuse of problems with the wiring of the beans.

I just want to add that this application works flawlessly if just use imports of the spring configs for all modules, but I would like to save resources and startup time by sharing the modules possible.

Any help greatly appreciated!
