The ModelExplorerViewModel is doing a synchronous call to the PersistenceService Login, but that method, in BasicPersistenceService, is actually performing an asynchronous login using EnitityManager.LogicAsync.  This works with null credentials because in this sample there's no IEntityLoginManager implementation to validate credentials.  DevForce itself accepts null credentials and creates a dummy GenericPrincipal to uniquely identify the user. 
 
To have DevForce enforce user authentication you should implement the IEntityLoginManager interface, and also set the "loginManagerRequied" flag in the ideaBlade.v4 element:
 
  <ideaBlade.v4 version="4.00" 
              clientApplicationType="Silverlight"
              loginManagerRequired="true"
              >

Hello,
 
After little digging in this example, i found that when the Login (sync) function is called, the login credentials are null. This doesn 't stop the callback (logged in?) to hit with success (logged in!) and the Principal member filled in correctly.
 
Could you please clarify what is going on?
 
On second view i found a region principal_id in the .ibedmx designer. Is this relevant?
 
Thank you
 
Andreas
