It all depends on how your authentication method is set up. I'm still a little fuzzy on all the details, but you can do a few different things. Each has its own pros and cons, and some combination is probably best.
- Each C::A could authenticate itself against a master set of authorities. The C::A would implement a check against a set of authorities the user must have. The link would exist, but the user wouldn't get very far.
- If you're using TT or Mason, you could pass in a $user object and have it determine what links are available, based on the $user object. (Not C::A specific, I know, but not everything is implentable in C::A, nor should it be.)
- Instead of the $user knowing what links it can go to, you would have the C::A indicate what authorities are needed to get to it. Then, it would register with some master and the $user / TT / something would ask that master where it can go.
And, I'm sure I'm missing other possible schemelets.
