注释

You can use the CredentialRetrieval property to specify where to retrieve the credentials that are to be used by the Report Server when connecting to an external data source.

There are four possible settings for this property:

  • None – The connection to the data source does not require connections. This is the least secure method of connecting to an external data source and is not recommended. Note   The UnattendedExecutionAccount must be specified in the RSReportServer 配置文件 file.

  • Prompt - The report server requires credentials. If credentials are not supplied, the report is not generated and an exception is raised.

  • Integrated- The report server utilizes the credentials of the user authenticated to the report server. Any other data source credentials supplied are ignored.

    注意注意

    If the EnableIntegratedSecurity system property is set to false, setting CredentialRetrieval property to Integrated will cause an exception to be thrown when the server attempts to retrieve data source credentials.

  • Store – The credentials are stored securely in the Report Server database.

There are a number of features of the Report Server that require the credential retrieval option to be either Store or None in order to successfully execute. These include schedule based features such Report Execution Snapshot generation, Report History generation, and subscriptions.

When credentials and the connection string are stored in the Report Server database, they are encrypted.
