How to restrict media section access?

Sunday 01 March 2009 5:00:43 am

I've defined policies and roles to grant a "group" only to have access (in admin interface) to a specific node and it's all ok.

Now i have a problem not solved yet.
When any user of this group edit an object and add an existing related object he's redirected to "Media" section (or anywhere else, i know i can set it), but i need he can only access to a certain folder under "Media" (but i must ensure the navigability of all media section).
I've not found any solution yet.

Note that:
I can't restrict access to a specific part of the structure because in this way he can't browse through out it.
i can't use "redirect after login" functionality, because i have different group using the same role (with tree limitation).

I hope it's clear enough.
Thank you
