Microsoft distributes Microsoft SQL Server 2008 fixes as one downloadable file. Because the fixes are cumulative, each new release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2008 fix release.
Symptoms
You have a SQL Server Reporting Services report whose data source connects to Microsoft SQL Server 2008 Analysis Services. The data source uses the Microsoft ADOMD.NET data provider together with the HTTP protocol for the connection. When you open the report by using a nonadministrative account, you may receive various error messages based on the credential setting of the data source in the Report Manager.
Credential setting 1
The data source is configured to use the Windows integrated security option. In this case, you receive the following error message:
An error occurred during client rendering.
An error has occurred during report processing.
Query execution failed for dataset '<DataSet Name>'.
The connection is not open.
Credential setting 2
The data source is configured to use the Credentials are not required option. In this case, you receive the following error message:
The current action cannot be completed. The user data source credentials do not meet the requirements to run this report. Either the user data source credentials are not stored in the report server database, or the user data source is configured not to require credentials but the unattended execution account is not specified. (rsInvalidDataSourceCredentialSetting)
Credential setting 3
-
The data source is configured to use the Credentials stored securely in the report server option.
-
The Use as Windows credentials when connecting to the data source option is enabled.
-
The Impersonate the authenticated user after a connection has been made to the data source option is not enabled.
-
The user who is specified for the data source has sufficient permissions in SQL Server 2008 Analysis Services.
For example, the user has the server administrator role.
In this case, you receive the error message that is mentioned in the "Credential setting 1" section.
Credential setting 4
-
The data source is configured to use the Credentials supplied by the user running the report option.
-
The Use as Windows credentials when connecting to the data source option is enabled.
In this case, you receive the error message that is mentioned in the "Credential setting 1" section.
Cause
When you open the report, the data source of the report connects to SQL Server 2008 Analysis Services by using the data source credential. After the connection is established, successive requests to SQL Server 2008 Analysis Services do not reuse the data source credential. Instead, successive requests use the credential of the current user. This causes the problem that is mentioned in the "Symptoms" section.
Status
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
