Using permissions, you can specify the users who can access your site and the actions that they can perform on the site. When you create a new site by using the Use unique permissions option, the Set Up Groups for this Site page is displayed. On this page, you can specify the users who can access your site.
Windows SharePoint Services 3.0 classifies users intothree groups—visitors, members, and owners. Visitors can only read the content that is displayed on a Web site. Members can create and edit content but cannot create lists or manage site membership. Owners can manage and maintain a site.
You can toggle a site between inherited permissions and unique permissions by clicking Advanced permissions under Users and Permissions on the Site Settingspage. Alternatively, you can click People and groups either on the Quick Launch or under Users and Permissions on the Site Settings page and then click Site Permissions on the Quick Launch. If you want to toggle to inherited permissions on a site that has unique permissions, on the Permissions page, on the toolbar, click Actions, and then click Inherit Permissions. If you want to toggle to uniquepermissions on a site that has inherited permissions, click Actions, and then click Edit Permissions. Windows SharePoint Services 3.0 displays a warning before the permissions are toggled.
A site that has unique permissions is not linked to the parent site. Therefore, you can add and remove users from the site irrespective of whether the users have permissions to access any other site. When addingusers to a site, you must either add the users to a SharePoint group or associate them with at least one permission level.
A SharePoint group is a collection of users and groups, such as Windows group and domain group, with a defined set of one or more permission levels and attributes. SharePoint groups are maintained at the site collection level. When a new user or a group is added to a SharePointgroup, the new user or the group is granted the permissions that are given to the SharePoint group on any site. Windows SharePoint Services 3.0 provides the following permission levels:
• Read. In this level, a user can only view a site.
• Contribute. In this level, a user can view, add, update, and delete the site content.
• Design. In this level, a user can view, add, update, delete,approve, and customize the site content.
• Full Control. In this level, a user has full control over a site.
• Limited Access. In this level, a user has permission to view limited resources on a site, such as specific lists, document libraries, folders, list items, or documents when given explicit permission.
