Ok...thank god I know where to look.
 
A quick search turned up the following cookbook document that solved my problem:

Given my lack of experience in Python, I think it might be high time to consider some deeper self-teaching on the subject because it would have helped me around this a lot sooner (and reduced the stress).

Greetings all,
 
Having done a stupid thing and experimenting with user authentication, I have managed to lock myself out of the folder controlled by a PostgreSQL User Folder.
 
I can access the top level (because it uses standard Zope authentication) but everytime I try to access the sub-folder with the above acl_users, it tells me it is forbidden.
 
Is there a way for myself to bypass the lower-level security so as I can remove this acl_users folder and reinstate it.
 
I've tried the Undo option to no avail.
 
Any help would be greatly appreciated.
