Hi Saba,
My first question is, why are you using such an old guide, are you integrating CA SSO with Identity Manager 12.5?
What is your environment like: version of IDM, application server used, OS, what is your CA SSO version and setup? How did you configure the proxy plugin for CA SSO and IM integration?
There are many things that may have been mis-configured on CA SSO, CA Identity Manager or even proxy plugin setup making it very difficult to help you troubleshoot the issue based on a screenshot. I highly recommend you open an issue and attach all your logs.
Also, I believe you will find more up to date documentation on docops. choose your IM version and go to CA SSO integration section. The latest documentation provides better instructions on some steps than the guide you are using.
