user rights

Clarifications

Do you want users to be able to access a share or do you want a user to be able to share a folder?

With what restrictions?

the user might have to be part of a global security group in order to access the folder, to which you must add the user to the group. Second thing: if that is not the case, you need to right click on the folder and select properties, from there click the sharing tab and select permissions, this is where you are going to select the user you want to share the folder also you will choose if they can read, change, or have full control over the file.......next thing you want to do is go into the security tab, add the user and set permissions.
