Hi MichielHelder,
I appreciate your patience - my apologies for the delay in responding initially.
If I understand correctly, you are looking for a way to see which users are assigned to a particular role, is that correct? If so, then the way to do this is to use the Policy Manager --> Tasks --> Manage Roles. This will then bring up all the roles which a user can be assigned to. If you click on one of the roles (e.g. Administrator), you will then see a list of "Assignments" on the bottom-half of the window which then lists all the users who are assigned the role you have selected.
There isn't so much of a report generator for that, but the information is indeed there in the Manage Roles area of the Policy Manager.
If I have missed anything or misunderstood your concern, please let me know and I will try to correct or improve my answer. Thank you, Michiel.
Sincerely,
Dustin Dauncey
