converted to an error code and reported to higher-layer protocols via the
return value.</p><p>This method deletes all connection security rules in the
connection security linked list of the memory representation of the store being
modified. It also writes through and deletes all rules from the disk
representation. If called on an online store, no connection security rules are
enforced after the method returns.</p><p>The server MUST validate that the client is authorized to
perform the requested operation (as defined in section <span><a href="b0c93352-8371-4d63-abca-b0cc8dbcc3d7" data-linktype="relative-path">3.1.4</a></span>)
