hi,
I have same issue.
Cannot add/update Relying Parties from the GUI from metadata files “Method not found”
So,I use powershell to set ADFS.Then,worked it.
But,I have other issue.
Sing-in ADFS,then redirect CRM.
Without manipulating the screen,then pop-up windows authentication.
It is not ADFS Authentication(CRM Extranal),It is Windows authentication(CRM Internal).
I am using other Internet line (CRM Extranal Access) to access CRM.
Why, after SSO lefttime, pop-up windows authentication?
