IFS permissions question

I have removed two users from all folders who are no longer authorized to my IBM i. I disabled their user profiles and removed their authority from all files and folders. When I attempt to edit a configuration file using the GUI I get the following error:
*Error:* ZUI_50008: You do not have the necessary authority to update configuration file */www/myapps/conf/httpd.conf*.

The myapps folder has the following authority:
*PUBLIC *X
PETE *RWX (and all object authorities)
QTMHHTTP *X (an no object authorities)

and the /www/myapps/conf folder has:
*PUBLIC *X
QSYS *RWX (and all object authorities)
PETE *RWX (and all object authorities)
QTMHHTTP *X (an no object authorities)

When I create a brand new HTTP server instance using the ADMIN GUI I see the following:
*Error:* ZUI_50009: An unknown error occurred attempting to update configuration file */www/testsec/conf/httpd.conf*.

The folders and files created by the GUI have the following permissions:
*PUBLIC *X
PETE *RWX (and all object authorities)
QTMHHTTP *X (an no object authorities)

I (PETE) have all authorities on the system.

Something was changed, perhaps by the user who had the original authorities on the folders and has now been removed. I would have thought that a "clean" creation of a new HTTP instance would have the correct authorities (which I think would have QTMHHTTP with *RXW and all authorities on all objects, correct?)

Where are the "controls" that determine what an HTTP instance has regarding authority? How do I fix this (is it a user profile issue on QTMHHTTP?)?
