Enable Single Signon for SAP EP with User Mapping
If you enable single signon with user mapping,
you define an IBM® Cognos® data source in SAP EP. Individual users
or an administrator can enter the user IDs and passwords for IBM Cognos components
in the data source. You must map the users logon credentials in the
data source to a namespace. Portal Services iViews transmit the logon
credentials to IBM Cognos components using HTTP Basic Authentication.
