Sharepoint 2010: Assign a user permissions to edit other users items without adding "Manage List" permissions

Question

In our Sharepoint we have the need to assign permissions to a user so he can edit the entries created by other users, while the remaining users maintain their current permission to add/modify/delete only their own created entries. We don't want to give this user "Manage List" permissions, only the permission to modify entries from other users. Is this possible? Thanks!

Answer 1

You cannot override the "add/modify/delete only their own created entries"

Answer 2

Create a new permission level as a copy of Contribute and add the "Manage Permissions" permission only. I call this "Contribute and Permissions Mod". Then assign your user this new permission level on the list.

Answer 3

You can run an Impersonation Step and do the highlighted line below in a SharePoint Designer (SPD) 2010 workflow. I created a custom permission that gave the users only create rights. Then assigned permissions based on some conditions.
