What's the correct way to reuse LDAP beans/connection settings?

[idwright]

I'm trying to create an action which accesses LDAP.

If I define the action bean in /extension/subsystems/Synchronization/ldap/ldap1/my-ldap-context.xml then I would normally expect to be able to access it using org.alfresco.repo.management.subsystems.SubsystemProxyFactory but that doesn't work for the Authentication subsystem.

Cannot convert value of type [org.alfresco.repo.management.subsystems.DefaultChildApplicationContextManager] to required type [org.alfresco.repo.management.subsystems.ApplicationContextFactory] for property 'sourceApplicationContextFactory':

If I pull the bean definitions (<import resource="classpath:alfresco/subsystems/Authentication/common-ldap-context.xml"/>) into my context/actions-context.xml then chaos ensues

What does work is to redefine ldapInitialDirContextFactory in the context file but that's not ideal.

Any thoughts?

Thanks.

You don't need to define your action bean in /extension/subsystems/Synchronization/ldap/ldap1/my-ldap-context.xml or import common-ldap-context.xml. You can define your action in regular way.

You can try to do it like this:
1.Make your action implements spring InitializingBean and In your action reference interface ChildApplicationContextManager
public class YourAction implements InitializingBean{
   private ChildApplicationContextManager authenticationContextManager;
   private LDAPInitialDirContextFactory ldapInitialDirContextFactory;
   public void setAuthenticationContextManager(ChildApplicationContextManager authenticationContextManager) {
   this.authenticationContextManager = authenticationContextManager;
   }
   @Override
   public void afterPropertiesSet() throws Exception {
   for(String contextName : authenticationContextManager.getInstanceIds()){
      ApplicationContext ctx = authenticationContextManager.getApplicationContext(contextName);
      try{
            ldapInitialDirContextFactory = LDAPInitialDirContextFactory)
            ctx.getBean(LDAPInitialDirContextFactory.class);
         } catch(NoSuchBeanDefinitionException e) {}
      }

   }
}
2.And in your action spring file inject Authentication bean to your action authenticationContextManager property
<property name="authenticationContextManager" ref="Authentication" />
3. override afterPropertiesSet method of your action and get ldapInitialDirContextFactory bean like previous code.

I see this has had quite a lot of views recently so thought it might be helpful to add a link to the implementation I ended up with:
