Azure AD B2C has the concept of Custom Policies, which in theory can be used to connect a B2C tenant to any IdP using SAML (see https://docs.microsoft.com/en-us/azure/active-directory-b2c/active-directory-b2c-overview-custom).
Google's GSuite (org-owned) system can apparently be connected to as an IdP using SAML (only SAML) (see https://support.google.com/a/answer/6087519?hl=en).
Has anyone successfully connected these so that end users could use their GSuite accounts to authenticate to enterprise application with Azure AD B2C in the middle?
thanks!
