Hi, I configured IWA authentication in Windows 2016 IIS 10, as the other coments says I configured IIS and tested with the SiteMinder Agent 12.52 sp1 cr8.
If i disable the webagent I can access my page authenticated sucessfully by IIS, I tested even with a SDM 17 that displays the user that was authenticated by IIS. In summary with ca sso agent disable the windows authentication works and I validated with a SDM 17
If I enable the agent
The browser the redirects to the following link
but doesn't give me the page that i requested originaly or request any credentials
I located another question about IWA that suggested to define the authentication also in the siteminder directory in IIS, I enabled in that directory from IIS windows authentication and disabled anonymous authentication, no matter if the default was also configured and worked
