Access rights for collaborative systems tend to be rather complex, leading to difficulties in the presentation and manipulation of access policies at the user interface level. We confront a theoretical access rights model with the results of a field study which investigates how users specify access policies. Our findings suggest that our theoretical model addresses most of the issues raised by the field study, when the required functionality can be presented in an appropriate user interface.
