SSO not working

SSO not working

We are trying to setup Active directory Pass-through authentication (SSO) http://kbase.zohocorp.com/kbase/ServiceDeskPlus/TroubleShooting/file_100009.html . 

However, it does not seem to be working. We still see the login screen(Same result in IE, Chrome or firefox) see that the computer account has been created in database and Active directory-> Computers.

More info : We had customized the login page. But we put the default page back without change. Our custom logo still appears despite resetting the login page.

There is no "failed" in the sso.log

Any idea ?
