CA Single Sign On 12.8 federation with Service Desk Manager 17

I downloaded the procedure to configure federation in CA SDM 17

https://docops.ca.com/ca-service-management/17-1/en/installing/post-installation-tasks/ca-service-desk-manager-post-installation-tasks/enable-saml-authentication-for-ca-sdm

I followed all steps, but when I try to access SDM , use this link to redirect to IDP on CA SSO

http://d1apcassoagw01.minedu.gov.co/affwebservices/public/wsfeddispatcher?wa=wsignin1.0&wtrealm=https%3a%2f%2fd3apservidesk%3a443%2fCAisd%2fpdmweb.exe&wctx=rm%3d0%26id%3dpassive%26ru%3d%252fCAisd%252fpdmweb.exe&wct=2019-01-14T23%3a11%3a52Z&wreply=https%3a%2f%2fd3apservidesk%3a443%2fCAisd%2fpdmweb.exe

I have an error , and I didn’t find documentation about how to configure the federation in the CA SSO Side, I created the local IDP in SiteMInder, but I don’t know how to configure the remote SP and the federation, so this link will be solved

Thanks
