SAP to OneIM using SNC

Has anyone set up a connection to any SAP system using SNC? We are running into an issue where it is not connecting and think it may have something to do with needing to exchange certificates between the systems. This would set up the trust relationship between the systems. I had added the sapcrypto.dll to the OneIM job server. Is there something I am missing? Also we are using OneIM 8.1.1.
