Alex Yang 2ac8e5d312 fix(sso): read SAML InResponseTo from correct path (#8607)
samlify's extractor nests InResponseTo under `extract.response`, not
directly on `extract`. The two login handlers (callbackSSOSAML and
acsEndpoint) were reading `extract.inResponseTo` which is always
undefined, causing InResponseTo validation to always fail. The logout
handler already used the correct path `extract?.response?.inResponseTo`.

Updated SAMLAssertionExtract interface to include the `response` property
with proper typing instead of casting to `any`.

About the Project

Better Auth is framework-agnostic authentication (and authorization) library for TypeScript. It provides a comprehensive set of features out of the box and includes a plugin ecosystem that simplifies adding advanced functionalities with minimal code in a short amount of time. Whether you need 2FA, multi-tenant support, or other complex features. It lets you focus on building your actual application instead of reinventing the wheel.

Why Better Auth

Authentication in the TypeScript ecosystem is a half-solved problem. Other open-source libraries often require a lot of additional code for anything beyond basic authentication. Rather than just pushing third-party services as the solution, I believe we can do better as a community—hence, Better Auth.
