Read the Permissions Page
The name of the file or title
for the item, list, or library appears in the page’s title after the
word Permissions. This information helps you make sure you are viewing
the permissions for the right file or item. The name of the user or
group is in the first column, and the type (identifying whether it is a
user or group) is in the second column. In the last column, you can see
the permission set that the user or group has on the item, file, list,
or library. Depending on the configuration of your server, other columns
with more information about the user or group may also appear.
For example, in Figure 10.2,
people in the SharePoint Team Site Visitors group can only read the
file or item because they have only the Read permission, whereas
SharePoint Team Site Owners can do everything to the file or item
(including manage the permissions on it, delete it, and so on) because
they have the Full Control permission set. The System Account
(SHAREPOINT\system) group is shown to have Limited Access permissions.
This type of permission can mean different things in different sites but
usually means read-only permission.
It is important to note that
if permissions are given to a group and then separately to a user, if
that user is a member of the group, the higher permission level wins.
For example, suppose user A is a member of group B, and group B has Full
Control permissions on an item. Although user A was given just Read
access, because user A is a member of group B, that user also has full
control of the item and not just Read access. The same would apply if
the situation were reversed: If user A has Full Access and that user is a
member of group B, which has Read-Only access, the user still has full
access to the item.
Check the Permissions for a Specific User or Group
A page’s Permission Tools ribbon, shown in Figure 2,
has buttons for managing the permissions of the parent (if the file or
item is inheriting from a parent), to stop inheriting permissions, and
to check permissions. Clicking on the Check Permissions button opens a
dialog that allows you to check what kind of permissions a certain user
or group has on the file, item, list, or library, as shown in Figure 3.
To use the dialog, simply
type the user name or group name in the User/Group box and click the
Check Now button. The dialog then shows you what permission levels that
person or group has on the file, item, list, or library, as shown in Figure 4.
