SSO for Solution Manager 7.1

Hi,

After configuration of SSO between backend system(ABAP) and front end (JAVA) of solution manager 7.1 and test i'm getting the login prompt with  error as in screenshot.

I have performed the below steps for SSO.

1).Generate certificate (SAPlogonticketkeypair.cert) in Visual Administrator of Solman.

2).Setup parameters "icm/host_name_full ","login/accept_sso2"_ticket (parameter value "1") and "login/create_sso2_ticket" (value 2) – Already existing

3) Import the above frontend cert into backend (Strustsso2), added to certificate list and ACL.

4).Export certifcate from backend(ABAP) and import into Keystore.

5).Added SID to security provider list for components "ticket" and "evaluate_assertion_ticket" in VAand trusted systems.

is there anything config that needs to be performed.
