Permissions tab
On this tab you can configure which permissions should be assigned to the given role.
To add permissions to the role, select the type of the permission that you wish to assign using the two drop-down lists. Once this is done, individual permissions for the specified module or document type will be displayed below and can be enabled by checking the corresponding boxes.
More information about roles and permissions can be found in Developer's Guide -> Development -> Membership, permissions and security -> Security model overview.
