Thanks Krishna,
This is an answer for part of the question, what user types I'd need to make in NW AS ABAP and JAVA.
I'm still looking for input from the community what actual roles one needs to assign in the NW AS ABAP to the user account that will be used in the NW IDM repository setup. Can anyone share with me how their users are set up for authorizations in their systems (ABAP and if available, JAVA).
Your link let me to OSS note 1557803, which says one need to assign role SAP_BC_SEC_IDM_COMMUNICATION to the NW AS ABAP user, and then Googling that, I found this help document with yet more roles (however in relation to a SAP Supply Network Collaboration system.
I'm still not sure which authorizations to use.
