SSO Configuration

Dears,

I need to configure SSO on our Netweaver 2004s server that contains ABAP+JAVA stack.I want to configure it for my ECC5 server.

Steps that I followed for it are:

Created a system and maintained all settings like Alias,user management,connector.

In System Administration >> System Configuration >> Keystore Administration >> Content

Download verify.der File

in my netweaver 04s portal server.

on ECC5

In STRUSTSS02 imported the certificate and Add to ACL and save.

But SSO is not working fine and Its looking to me that something is missing in my configuration.

Please check my steps and suggest what i am missing.
