Configuration of the web proxy server (CA Siteminder 12.52 SP1 CR10 with Apache Jakarta redirector to forward requests to the IMS), attempted to access the user console of the IME. Instead of seeing the usual landing page with the left-hand menu, only see the top banner and an animated GIF progress bar that reads, "Please wait."
Component : Identity manager 14.3, Siteminder: 12.52 SP1 CR10
The issue was caused by a custom CSP (Content Security Policy) header. When the content was attempted to redirect to IDM through IIS. CSP filter HTTP response which results in not being able to load js.
This is outside the scope of L1 support.
You will need to Modify the CSP header to add directive 'unsafe-eval' and 'unsafe-inline'
