SAML: A fractal of bad design

    SAML sucks, but it still has a bunch of features for its specific narrow enterprise SSO use-case that OIDC lacks - most notably IdP-initiated flow. OIDC is a constellation of specs with inconsistent support across products, whereas the commonly-implemented subset of SAML is more-or-less stable in its mediocrity.

    OIDC will eventually displace SAML, but if you're selling to enterprises you should really support both. Both will pale compared to the amount of time you spend dealing with SCIM inconsistencies between IdPs anyway.

      What is prventing OIDC-based IdP from initiating login? You just need to know the login URI:
