This evening a fix migrates to production that should prevent Cognos from reprompting for login credentials as it sometimes has been doing.  This is for the Public Folders and My Folders links, under REPORTING in the CU Resources tab in your campus portal – the two links from portal to Cognos (see https://content.cu.edu/controller/traininghelp/stepbystep/reporting_logging_in.html).  Clicking either of these links should take you directly into Cognos without having to log on again.
