Hello, In my application, I want a feature where user can delete some system privileged files. To achieve this, user need admin privileges i.e. user need to enter admin username and password. My question - Is there any other way to provide the admin privilege to the user, if user doesn't know the admin username and password. Please guide. I have also read previous discussions on this topic ( http://forums.macrumors.com/showthread.php?t=658751&highlight=authorization ) and understood that user has to know admin credentials to perform this task. Thanks, Tejashree.
