Allow users to "edit permissions" on their own documents

Question

We have a customer who expressed a need to allow the "Author" of a document to edit the permissions of that specific document, without giving him/her the "Edit permission" - permission in the entire library.

Is there any way to achieve this, without breaking inheritance on each separate document and manually/programmatically edit permissions?

Answer 1

AFAK it is not possible to implement that without breaking role inheritance. You can automate this using a sharepoint designer workflow as shown in example here.
