Config SDK Permissions

[PFCCWA]

Hello,

We are using a configuration SDK via GIS however when running the client, we receive messages like these.

[i]</description></serverErrorInfo></errorInfo></responseItem><responseItem id="AddAgentToAnotherFolder"><errorInfo returnCode="2233865"><serverErrorInfo><description xsi:type="xsd:string">Insufficient permissions to perform this operation</description></[/i]

In the case above, an agent is being moved from one folder in Persons to another.  The IDs are correct within the code snippet so based on this I would presume the permissions for the objects affected are not correct.
But after checking this I have given as much as full control to the access group to the folders (old and new) BUT only read permissions to the Persons folder - is there anything more which needs to be given, or changed?

Persons                            <<<<< Read
Persons sub folder X, existing <<<<< full control
Persons sub folder Y, new      <<<<< full control

note sub folder Y is a sub folder of X.

thanks,
