I have integrated successfully CA Business Intelligence JasperReports Server with Spectrum and enabled SSO (Single Sign On) and configured it for Internet Explorer (IE) based on knowledge document KB000006850 "Jaspersoft SSO Integration is not working with Internet Explorer" located at https://comm.support.ca.com/kb/jaspersoft-sso-integration-is-not-working-with-internet-explorer/KB000006850
This is an issue due to IE's Compatibility View functionality.
Disable IE's Compatibility View by clicking top right Tools (Gear) icon -> Compatibility View Settings. Compatibility View Settings window will be displayed. Deselect both "Display intranet sites in Compatibility View" and "Use Microsoft compatibility lists" check boxes. And then you can refresh the JasperReports page.
Internet Explorer 11.0 is supported Web Browser. However, Mozilla Firefox and Google Chrome are recommended web browsers.
See Supported Web Browsers in CA Business Intelligence JasperReports Server 6.3 documentation.
