I am trying to set up a back-end login using Microsoft 365/Azure AD login provider.
I have set up the tenant and application using the documentation from here: https://doc.dynamicweb.com/documentation-9/users/external-authentication/microsoft-365-azure-ad#sideNavTitle1-2
However, when I try to log in from back-end, I get this message and nothing happens after it:
Is this external provider still supported? I am using DW 9.16.5. How do I debug it further?
