EBS SSO: EBS + OAM + OID + Tivoli

Hi,
I want to integrate EBS with IBM Tivoli for SSO. I have studied some docs, installed and configured a test env  (EBS 11.5.10.2 + OAM 11.1.2.2.0 + OAM WebGate 11.1.2.2.0 + EBS AccessGate 1.2.3.4 +  + OID 11.1.1.7 + Tivoli 6.2 ) according to Document 1536941.1.

Now, when i access EBS, it will redirect to OAM login page, enter the valid username and password which created in oid, then linked a user in EBS ,i can access EBS reource.

That is to say, I have realized the integration of EBS + OAM + OID, But i don't know how to continue realize integration with IBM Tivoli Directory Server. Could you show the way to do this ?
