DataHub for Users/UserRoles

Has anyone tried using DataHub to share Users or UserRoles between applications? We have a few applications that we must reduntantly add the same users and user roles to. I thought maybe we could publish th User/UserRole data from one app, which technhically is possible. The subscribing applications can see these entities. The problem is they don’t seem to REPLACE the Users/UserRole entities in these subscribing apps. You can’t drag the DataHub entities into the System domain model, you have to put there in a custom modile, creating a duplicate entities that, while named User and UserRole, doesn’t serve the same roles.

This will simply not work, as the System module is read-only.

What you are looking for is a SSO (single sign-on) solution.
