What is the resolution to error while making SNC connection to SAP Netweaver AS ABAP?

Hi,

We are integrating IBM Security Identity Manager (ISIM) with SAP Netweaver AS ABAP 7.3 (SAP Nw). For integration, we are using ISIM SAP Netweaver Adapter (SAP Nw Adapter). SAP Nw Adapter makes use of IBM Tivoli Directory Integrator (ITDI) for communication with SAP Nw.

We have installed SAP Nw, ISIM and SAP Nw Adapter. However, when we are trying to make connection from ISIM server to SAP Nw via Adapter, it is resulting in below mentioned error in TDI logs:

RMI TCP Connection(4)-192.168.87.156 [15:59:42:710]: [JCoAPI] JCo version is 3.0.15 (2016-07-26)
