📄 Description

addresses https://github.com/better-auth/better-auth/issues/7693

Summary by cubic

Adds a shared redirectURI option for OIDC SSO so all providers can use a single callback URL, simplifying IdP setup and migrations. Introduces a shared callback endpoint and updates state handling while keeping per‑provider callbacks working.

  • New Features

    • New sso({ redirectURI }) to use one OIDC callback for all providers; accepts relative path or full URL.
    • New shared endpoint /sso/callback; providerId is read from OAuth state.
    • Provider registration returns the shared redirectURI when set.
    • Exposes callbackSSOShared in the plugin; docs updated and tests cover the shared flow.

  • Refactors

    • Centralized OIDC callback logic into a shared handler used by both per‑provider and shared endpoints.
    • Added getOIDCRedirectURI; signInSSO stores ssoProviderId in state and uses the shared URI when configured.
    • SAML: Buffer-based base64 decoding, safer final redirect handling, improved default name, and consistent provisionUser execution.

Written for commit 4bb784efc7. Summary will update on new commits.
