问题:

Our current application is authenticating users with a SAML IdP. We wish to retain their implementation of SAML and update the application’s configuration with Azure AD B2C, not switch to OAuth2 or OpenID Connect. Does Azure AD B2C currently support receiving authentication requests via SAML? I am unable to find this in the documentation.

回答1:

Azure AD B2C does not support integrating with applications / relaying parties via SAML yet.

You can support this ask and keep up to date on its progress by voting for it in the Azure AD B2C feedback forum: (Application) SAML Protocol support.

回答2:

Azure B2C does (has for a while) provide SAML connectivity through custom policies in the Identity Experience Framework currently in public preview - https://docs.microsoft.com/en-us/azure/active-directory-b2c/active-directory-b2c-overview-custom
