Centralized security within the Cognos BI Suite is delivered by Access Manager. Access Manager allows single-point management of user classes and profiles for all implemented components of the suite from a central console. Both authorization security and logon (or authentication) security is addressed. Access Manager can be used standalone to manage the information that your organization’s consumers can view, or you can combine your Access Manager configuration with database security and OS security to reach the desired level of user authentication. I have seen many diverse combinations of RDBMS, OS, and / or LDAP security put in place at various clients for authentication over recent years.
