Abstract:
1. A method for replacing an Access Control List (ACL) of a managed node, comprising: receiving by a terminal, a command from a Device Management (DM) server for replacing an Access Control List (ACL) of a managed node on a Device Management Tree (DMT), wherein the DMT comprises a plurality of levels, each level comprises at least one node, and the managed node is an internal node on the DMT, wherein the internal node comprises at least one descendant node; determining by the terminal, whether the DM server has an authority to replace the ACL of the managed node according to the ACL of the managed node; if the DM server does not have the authority to replace the ACL of the managed node, determining by the terminal, whether the DM server has an authority to replace an ACL of a parent node of the managed node according to the ACL of the parent node; if the DM server does not have the authority to replace the ACL of the managed node and the DM server does not have the authority to replace the ACL of the parent node of the managed node, determining by the terminal, whether there exists an ancestor node of the managed node which is one or more level above the parent node of the managed node on the DMT, and wherein the DM server has an authority to replace an ACL of the ancestor node according to the ACL of the ancestor node; if such ancestor node of the managed node exists, replacing by the terminal, the ACL of the managed node according to the command without replacing both the ACL of the parent node and the ACL of the ancestor node.
