I just implemented IDM 4.5 with OSP on tomcat and User application Websphere. It was working fine untill i moved OSP from 8080 to 8443(ssl) port .
Now when i am accessing the my user application url it is redirected to OSP login page , but after entering credentials it s give me the below error
An error occurred while attempting to contact the authentication service.

I know it is some certificate import issue , but cant figure where i need to make the changes

Waiting for some suggestions
