Delegated Users

In our current UCR arhcitecture, we use two installations. We have one machine with Access, Registry and Edges and one machine with the ODS. On the machine with the Registry, I can create a user/clinician. When I log into the management portal with this user, a so-called delegated user is created in the cached users table. So far everything is going well. 

When I try the same on the machine with the ODS I get the message : 'ERROR #822: Access Denied' . so no delegated user is created.... Does anyone have any idea where I can find the solution?
