      summary: Initiate SSO Authentication (Service Provider-Initiated Flow)
      description: 'Initiates the SSO authentication process by redirecting the user to their configured Identity Provider (IdP).


        What this endpoint does:

        1. Looks up the SSO configuration based on the user''s email domain

        2. Generates a SAML authentication request

        3. Returns the SAML request in a 200 or 303 response depending on request parameters


        Note: This does not authenticate the user directly. It starts the redirect flow to the IdP.
