I'm trying to set up claim-based authentication.
I've used
this resource as a basis for my configuration. ADFS itself is running fine as another application which I've been developing uses ADFS login and that works well.
However, after following that guide and attempting to log into CRM, I am greeted by a regular login prompt. No matter what I type in (be it a valid user account or an administrator account), I receive a 401 error.
All I know is that it's the ADFS server which is showing me the prompt (after CRM redirection). No errors appear in the Event Viewer (neither on the CRM server nor on the ADFS server) which would correspond to what I'm seeing on the screen.
What could be the issue? How should I approach this problem?
PS. When looking for similar issues, the most common one is about expired certificates for year-old deployments. This is not the issue - the deployment is new, and so are the certificates!
