We just upgrade jasperserver from 4.0.0 to 5.6 followin the Upgrade Guide. Everything seemed to go smoothly, the upgrade script completed successfully. But then, I started up tomcat and went to the app page, but it will not allow me to login with any of the user credentials we have, including jasperadmin. The error is "Invalid credentials supplied." I don't see anything in /var/log/tomcat7 related to this. Any help would be appreciated.
