When using the TIBCO Spotfire® Connector for Microsoft SQL Server to access a Platform as a service (PaaS) Azure Microsoft SQL Server database (see What is PaaS? for more details), the following error may be seen. This issue will be seen when the data connector authentication mode is set to "Kerberos" in the "Spotfire.Dxp.Worker.Host.exe.config" for Microsoft SQL Server (see the connector configuration examples for Spotfire.SqlServerAdapter for more details) and TIBCO Spotfire Server authentication is set to Kerberos with constrained delegation.

Could not load on-demand data

An exception was thrown by the data connection.

This article explains the "AdalException: Access is denied" error which is seen when using the TIBCO Spotfire Microsoft SQL Server data connection to access a Platform as a service (PaaS) Azure Microsoft SQL Server database.

To resolve, change the adapter mode to "WebConfig" for the Spotfire.SqlServerAdapter data connection, as described in the connector configuration documentation.  Note: You must also specify the credentials profile to use when logging in. This is done in the DataAdapterCredentials settings section in the configuration file. See the "DataAdapterCredentials" section of the reference for more details.

Kerberos mode will not work in case there is constrained delegation enabled on the TIBCO Spotfire Server. This is because in a PaaS Azure SQL Server database, there is no way to enable delegation to a service, for the service account. Alternatively, in case there is a need to enable delegation for the Node Manager service account, Infrastructure as a service (IaaS) Azure database should be used instead of PaaS.

Note: In this situation where the TIBCO Spotfire Spotfire is set for Kerberos with constrained delegation, the data source itself will also need to be set for constrained delegation.
