As per documentation https://docs.tibco.com/pub/sfire-analyst/latest/doc/html/en-US/TIB_sfire-analyst_UsersGuide/connectors/cis/cis_cisco_information_server_connection.htm using Spotfire Server it is possible to configure a common authentication domain with Tibco Data Virtualization Server. However, this functionality is not present in Sportfire Cloud, users are therefore forced to perform double authentication (one to spotfire cloud and the second to the TDV data source).
To improve the user experience it would be useful to have a common IdP between spotfire cloud and the tdv server.
Thanks!
