title: Using Relationships with Multiple Entity Managers
body: <p>I am wondering if it is possible to create a relationship between two entities that reside in separate databases. </p>
  
  <p>For example if we took the solution found here <a href="http://symfony.com/doc/current/cookbook/doctrine/multiple_entity_managers.html" rel="noreferrer">http://symfony.com/doc/current/cookbook/doctrine/multiple_entity_managers.html</a> and created a one to many relationship with Users in the customer database to Posts in the default database.</p>
  
  <p>Is this something that is supported by Symfony2 and Doctrine?</p>
