This topic may be closed, Microsoft told me that Microsoft Entra SAML Toolkit is getting deprecated, and I could use Claims X-Ray in the mean time instead:
Entra/Azure AD SAML Toolkit registration error
I am following https://learn.microsoft.com/en-us/entra/identity/saas-apps/saml-toolkit-tutorial#assign-the-azure-ad-test-user, I have created Microsoft Entra SAML Toolkit as an Enterprise SAML SSO app and configured it. I have created the user B.Simon@rivmnl.onmicrosoft.com and made it a member of the app. I now want to register with that same user under https://samltoolkit.azurewebsites.net/ , but I get the following error message:
Similar topics I have found about this under learn.microsoft.com did not provide clear answers or confirmations of resolution.
Logging in with this user under that website results in the same error message. I have also setup the Reply URL and the Sign on URL, and have downloaded the Raw SAML certificate and viewed it.
How can I troubleshoot and resolve this registry error?
