[Engine-devel] Problem in ovirt-reports sso

Hello, I have a reports problem which has got me for many days now. The reports sso feature is not functioning in my invironment. I followed the steps from the wiki page: http://www.ovirt.org/How_to_setup_a_oVirt_Reports_development_environment http://www.ovirt.org/Features/Design/Reports_Dashboard and the patch related to sso: http://gerrit.ovirt.org/#change,3355 here is my steps: 1. install jasperreports 4.7.0 using the bundled tomcat and the existing DB 2. modify the db password in ovirt.xml 3. import the reports using js-import.sh 4. add the EngineSimplePreAuthFilter in applicationContext-security-web.xml 5. add Reports.xml to the wenadmin folder and change RedirectServletReportsPage in db 6. generate a keystore using keytool and update EngineSimplePreAuthFilter in applicationContext-security-web.xml 7. install the ovirt-dwh rpm package made from source and run ovirt-engine-dwh-setup 8. start the ovirt-engine service and the tomcat And all the projects, ovirt-dwh, ovirt-reports, ovirt-engine, is build from the latest source. When I browse to the dashboard in webadmin portal,it just shows a jasper login page, so the sso is not functioning, right? I can login and browse jasper reports in a browser page normally. So I try to login in dashboard using reports user, tomcat gives me a Exception: "java.lang.IllegalArgumentException: An id is required to lookup a FlowDefinition" What might be the problem? Am I missing anything? Any help would be appriciated, thanks.
