We have a client who would be deploying a Rio deployment into both a test and production environment.  Their test environment includes a completely separate active directory infrastructure.  While this is a best practice in terms of their test environment (having a completely separate AD environment), from a LF named user licensing perspective, it means that even using Directory Named Users, they would still have to purchase separate named user licensing for test vs production (as AD users are in different domains), and as a result are concerned about the additional expense.  While they don't have to have the same number of named users in test, only enough for a representative sample for testing, they still are concerned about the associated costs.  

Does Laserfiche have any other options or solutions in this scenario other than purchasing separate named user licensing for test environment?
