[Zope] Creating a NeoBoard forum on a Python Script

Hi! I have a DTML document that calls a python script upon post. Somewhere on this python script I want to create a new NeoBoard Forum. What I did was to simply include the following code: context.manage_addProduct['NeoBoard'].manage_addNeoBoard_NB(forum_id, forum_title, forum_desc, 'default', 'MailHost') When I pressed the submit button, which would call the python script, a logon window poped up, asking me for a user/password. Is this some kind of authentication/permissions problem? How can I fix this? kind regards, Vitor Varalonga
