Permissions question

Hi All,

My question is: what permissions need an user to be able to create users (using code, not the interface for users administration)?

This is my problem. I created a page (part of a CUG) to create users, all my users are stored in the same location /home/users/appFolder/<user>. The user that access this create users page has read, modify and create permission over the folder of the users (/home/users/appFolder) but on publish it's throwing an error: "[RepositoryException] processing the function: WSCController.createUser javax.jcr.AccessDeniedException: Permission denied.", author mode works fine and my code does the job. Am I missing something?

Regards!!
