In Spotfire Analyst client 12.1 and greater, the following prompt will be seen when lauching the Information Designer from the Analyst Client. This is only applicable if your Spotfire Server uses Kerberos authentication.
This is accessed from Data -> Information Designer
At the time of writing this article (02/23) this is known product defect awaiting resolution. The issue occurs because a seperate java process for information services in launched in versions 12.1 and greater. This process is unable to receive authorisation headers from the client session.
A workaround is to stop the seperate java process for information services and keep this within the main TIBCO Spotfire Server process.
This can be achieved as follows:
1) Login to the Spotfire Server and export the confguration.
2) Disable Information Services launching as a seperate process.
config.(bat|sh) set-config-prop -n information-services.external-process.enabled -v false
3) Import the new config
config.(bat|sh) import-config -c "Disabled IS launching as external process"
4) Restart the Spotfire Server
Information Services should now launch without being prompted.
