I've considered this idea for a while. Imagine that a VineType Pro user wants to grant admin access to multiple employees or multiple members of his or her organization, and this [primary] admin wants to restrict their [additional] admin access rights to certain sections.
One way to do this would be to allow for certain dataname / value teams in the vinetype.config file, such as:
The first value would allow an additional login, so that if, for example, its value was "dougj" then in addition to the "?login=admin" login, then "?login=dougj" would also work.
The second value would be the password to authenticate against.
The third value would be a delimited list (maybe "pipe" delimited, like the $section_priority list) showing what section or sections that person has permission to edit.
Any business or organization that desired to have a team helping to manage their online VineType content, could predefine (in the config file) who the team members are and to what areas they should have access.
This feature could also allow per-user tracking of who created and/or edited a given article by username.
You may have already considered something like this. If not, this is just a thought to consider.
