Overload permissions for specifics users On my website, I have users with classic roles, but I want to add the possibility to assign permissions to specifics users. For example, a user has a role that doesn't allow the user to create articles, but I want to have a checkbox (on the edit page of the user's account) to grant this permission (and not to all users that have this role). Of course I can't create a specific role for that because I'm talking of many permissions specifics to users.

How can I perform this ?
I came across a similar situation and I think my is solution either the Group module or the og module. I didn't try them yet but both seems promising. I'm about to try them now.
