Hello
I have an identical issue . applied note SAP 1616121 . as Integrated AD with GRC 10.1 and SAP NW 7.4 portal.
However SAP recommended to remove Target CUA connectors to bring in SAP NW portals Systems.
On doing this , request gets provisioned only if the id exist in CUA .For a new account GRC cannot process this request .
Any suggestions on this
