For the SDM Reports tab to work successfully, all you need is a match between "userid" in SDM with "username" in CABI.
Creation of such usernames could be done either manually, or integrating with LDAP/AD (or some sort of SDK automation using Business Objects Enterprise C++ or JAVA APIs). Most SDM customers integrate it with LDAP, so the users get created per certain group/member criteria.
hope this helps
