Page Security requiring multiple roles

Page Security requiring multiple roles

  
Hi,

I am trying to solve an access control problem using our existing infrastructure.  Most of our clients fall into roles "Supervisor" or "Student".  Supervisors can purchase a sort of "premium" access to our services ("Subscriber") that applies to their account as well as those of who they supervise.  I have roles populated for "Student", "Supervisor", and "Subscriber".

I am trying to set access control to a page where only clients who are in both the "Supervisor" role and "Subscriber" role (i.e. they must be in both) and I would like to do this without creating an additional role of "Supervisor Subscriber".

Is it possible to specify access control where multiple roles combined are required?

Thanks,

Owain
