"Request Failed" when logging into /sigma/app/index#
This is a problem with the configuration of the SSO agent.
For example, the problem is in the call for "https://signintest.myco.com/sigma/rest/resources/USERPIC/iibgw.jpg". This call fetches the user image. It is responded with 401 (unauthorized) because this directory is protected.
Please refer to the page "Protecting CA Identity Portal with CA Single Sign-On" in the product documentation and make sure the configuration matches what it describes:
Pay special attention to fact that the "/sigma/rest/resources" realm should be protected and that the Agent Configuration Object must have the exact same IgnoreExt as in the documentation - ".class,.fcc,.scc,.sfcc,.ccc,.ntc,.css,.js,.woff,.woff2,.svg,.ttf,.eot,.json", see that "jpg" is not on that list.
This should solve this issue
