hello angela, I tried different variations of security configurations but find no solution that works for us. we would need a configration, where users are defined outside a workspace (e.g. as it works with the DefaultSecurityManager) but where ACLs are managed in the particular workspace (users could have different access-rights for different workspaces).
is there a possibilty to implement the behaviour needed by overriding some methods of the DefaultSecurityManager or is there now way for such a solution? best regards ferry -----Ursprüngliche Nachricht----- Von: Angela Schreiber [mailto:[email protected]] Gesendet: Freitag, 11.
