I was hoping someone could advise if it is possible in a federated CRM Online setup to NOT require an end user (internal network connected) to enter their username at the CRM Online login page before being redirected to AD FS for authentication i.e. the user clicks on a saved/published CRM Online link and is automatically logged on.
I found the following blog, https://blogs.msdn.microsoft.com/girishr/2012/09/05/dynamics-crm-identity-federation-demo-setup/ , which mentions this is possible but this does not work, this is an old post using AD FS 2.0 and a previous version of CRM Online. The specific quote in the blog I am looking to achieve is "You can also create single sign-on URL that allows users to login to CRM directly without even entering the username. This is done by appending the CRM URL with whr query string: https://crmpmg0.crm.dynamics.com/?whr=http://crmofeddc.crmpmg.com/adfs/services/trust"
