[Zope] Permission for a method

Hi, is there a permission that prohibits access to the "manage_renameObject" method? I'm currently facing the following problem: Just the superuser can create a new document and can set an ID for it. If a user creates a document and sets an ID, an error occurs. Something like "AttributeError" and "manage_renameObject". If the user doesn't enter an ID and lets it generate automatically there is no problem. Has someone any ideas? regards Lars
