I have truble with the permissions (get the message: "Authorization failed. Retry?") when I do the following:

Anwser: An attribute name must never start with "_". Though, it has not been your intend, "_" is used as an attribute name in "existingFolder._". What you should use instead is: _.getattr(existingFolder,folder_id).manage_addFolder('subFolder') Keep in mind for the future, that the right operand of "." is always a name and never an expression! When you want to use an expression, you will use "getattr" instead. Dieter
