MaharaUK11: LUNS Isolated Institutions
Previously called 'Walled Gardens', allows institution administrators to prevent users from seeing users in other institutions. There are benefits of centralisation: server config, theming, easy to join up users if you want to etc. LUNS designed it for CLEO. Can establish trust relationship between organisations. People can be members of more than one institution, and Mahara allows the most permissive of permissions.
