I'm trying to configure the Microsoft Portal add-on for Dynamics 365 to work with an external identity provider that supports SAML2.
I've followed all the steps as described in the documentation: https://learn.microsoft.com/en-us/dynamics365/customer-engagement/portals/configure-saml2-settings
The portal is correctly redirecting me to the identity provider login screen, I enter my credentials and then I am redirected to the URL specified in the AssertionConsumerServiceUrl site setting, which should be: https://mycustomportal.microsoftcrmportals.com/signin-saml2
At this point, we get a 404 and we do not get logged in.
I tried setting up the SAML2 Azure AD settings which take us to a different endpoint (https://mycustomportal.microsoftcrmportals.com/signin-azure-ad) and it works as expected.
Has anyone had any luck in getting the generic SAML2 sign in working?
