Thx very much Donka/Ridouan
One more question , if we have multiple ABAP and JAVA systems do we need multiple users/SPN created for each abap/java system or just one enough which would be mapped to where the Secure Login Server is and we export the ABap/Root Certs to ABap systems and Root Certs for each JAVA instances and do the user mappings .
Thank you
