A system and method for permitting a user of a business intelligence reporting system to be authenticated against one or more logon IDs and concurrently using access rights associated with those logon IDs in a terminal session. The user in a single terminal session is allowed to access the system with one of the logon IDs, a first logon ID, which gives that user access rights to data sources (or authorities) related to the first logon ID. The user may then add or remove further access rights by logging on or off with subsequent logon IDs. Each subsequent logon ID gives that user additional access rights to data sources related to the subsequent logon IDs. No attempt is made to reduce the number or change the nature of these logon IDs.
