When using SP initiated Login by typing in the Clarity URL http(s)://ppm.server.com/niku/nu, the request is authenticated by IDP and the browser keeps looping, sending the request to http(s)://ppm.server.com/niku/nu again and again.
Release : Any
This is caused by incorrect configuration of the HTTP(S) entry URL in NSA when a Load Balancer is used.
In NSA/CSA -> Application tab, make sure that the Entry URL is configured with the Load Balancer URL (https://ppm.server.com) instead of the Server URl (https://hostname.server.com)
