Infoview on tomcat with WinAD Authentication unable to configure SSO.

Hi, we have recently installed BO XI 3.1 with tomcat as app server and configured infoview with WinAD authentication with Kerbros. Now trying to enable Single Sign On, requirement is to end user login into their machines with domain account should not prompt for user/pwd, we are trying to enable Vintela for sso but its not working, getting tomcat 404 error and tomcat log shows. Appreciate your response.
