Hi!
Is it necessary to configure permissions to SHAREPOINT\System account on SharePoint sites?In which cases?
(I faced the case with our customers - they've limited permissions to SharePoint\System account. So, the code in our web part that runs under SPSecurity.RunWithElevatedPrivileges throws accessdenied exception when it try to add an list item. I try to understand - is this our omission or they have wrong permissions)
