Hi Frzs, I have created one test user and assigned manully created persimission that has persmissions are List Permission : 1) View application pages Sites Permission : 2) browse user information 3) Use Remote Interfaces 4) Use Client Integration features 5) open but problem is that even i assigned this normal permission to user still he can delete a others document from document library

Check to see if your test user is in another Active Directory group that has the permission to delete. I'd start by looking to see who is in the Contributor level group. -victor

Hi, Check the effective permissions of the user. You can use SecurityReportAccount functionality provided with AdminToolkit. You can get the admintoolkit here: http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=14227 I hope this will help you out.Thanks, Rahul Rashu
