I try to get Azure AD B2C working on Mendix. We have it working with the normal Azure AD this is quite easy because all is done in a gui. For Azure AD B2C this is done in XML so a bit harder.
I have followed the next tutorials and this works all. https://learn.microsoft.com/nl-nl/azure/active-directory-b2c/custom-policy-get-started https://learn.microsoft.com/nl-nl/azure/active-directory-b2c/connect-with-saml-service-providers
If I try now to get it working with mendix I get the next error:
Application registered corresponding to IssuerUri "https://xxxx.mendixcloud.com" in AuthRequest does not have assertion consumer service URL "https://xxx.mendixcloud.com/SSO/assertion" specified in its metadata.
In the SAMLApp1 Manifest, I put the Mendix Metadata URL. That is the only thing that I need to change so far I can find.
Can someone maybe help?
In the SAMLApp1 Manifest you must change the identifierURI to https://xxxx.mendixcloud.com (issuer in the SAML request from mendix).
The metadata at 'https://xxx.mendixcloud.com/SSO/assertion' must have an ACS URL within it.
