Distributed architecture considerations (advanced)
To complete the two-step delegation process from the user s computer to the
Reporting Server and back to Analysis Services, you can use one of the following
two options:
Enable the Kerberos protocol to allow credential delegation over multiple
connections. For more information, see the Microsoft knowledge base article
entitled, "How to configure SQL Server 2004 Analysis Services to use Kerberos
authentication" at http://support.microsoft.com/kb/917409.
Configure the reporting services data sources to use stored credentials or
prompted credentials to access the analysis services cubes. If you use stored
credentials, all connections from reporting services to analysis services occur
in a predefined user context. Also, role-based filtering does not function as
documented.
