Entree solution: Cookiemonster interface Goal: Virtual Learning Environments and Learning Management Systems shall be connected to Entree using easy to implement webservices. • Requirements: • No need for ‘foreign’ software in system • Native authentication of user by VLE/LMS • Standardisation of user attributes sent to Entree • For security purposes assertion of trust needed Consequence: No standard (eg SAML 2.0) fit the bill on ‘easy to implement’ due to maturity differences in VLE/LMS providers.
