Enabling SSO for Integrated ITS

Hi,

Are there any specific settings to be made to enable SSO for Integrated ITS.

We have configured the ECC backend system to accept tickets.

The profile parameters have been set. Certificate for EP has been added to ACL.

But when we create transaction iViews (which in turn use ITS) I am getting a screen, SSO is not active in the system.

Are there any settings other than this,specific to ITS that have to be done.

Thanks and Regards
