SSO Logout Session Not Invalidating: Users Re-Authenticated Without Login Prompt After Sign-Out- TS023011524

SSO authentication is functioning correctly from both the TSNext portal and direct CP4D access, but session termination behavior is inconsistent. Users can log in successfully and receive a logout success indication, however a subsequent access attempt to the same URL from a new browser window re-authenticates them automatically without prompting for credentials. This indicates the IdP/SP logout flow is not fully invalidating the federated session, and the logout callback/redirect handling is likely incomplete or misconfigured. We are treating this as a session invalidation gap in the SSO sign-out path and recommend validating logout endpoint registration, post-logout redirect URI configuration, token/session revocation behavior, and browser cookie cleanup across both TSNext and CP4D domains.
