Hi Narendar,
Outside of looking over JRK's posted URL's, are you able to SSO with the service account name & password in the Tomcat java options screen? This is the step, right before creating the SSO ticket on the Windows AD domain controller, to verify everything is working as expected.
If it's not working, I would go back through the configuration and ensure everything is configured properly. You can verify it by following along the second article that JRK posted up.
Let us know what you find. Thanks,
-Victor
