The Scenario :
get this php filemanager :
http://phpfm.sourceforge.net/#downloads
simply unzip into your web site directory
I have vhosts under a /data dir
rights 711 on the vhost dir, all fine
drwx--x--x 19 john data 4096 Jun 24 15:35 www.test.com
after calling the php file manager http://site.name/index.php
the rights on the directory are made world writeable
drwxrwxrwx 13 john data 4096 Jul 4 15:39 www.test.com

The problem is phpfm then.

Switching between suphp and mod_php didtn change anything .. the rights
on the dir are changed no matter
(the error above are with suphp enabled, with mod_php I didnt get any
error but the same result)
I have doubts that Apache (user apache) is able to change filesystem
permissions when it does not own a directory and no extension like suphp
is configured or suExec is set.
On FC4 the problem didnt occur

I didnt trace and debug the thing yet, pretty in a hurry right now, to find out what may have caused it ... if any1 heared about it .. ?
I would say phpfm is broken or misconfigured. I miss the proof that a
plain FC3 Apache2 with only mod_php - no suPHP, nor running suExec with
PHP cgi scripts - is able to change filesystem permissions for
directories / files the apache user does not own.

Yes it has been rebuilt using
httpd-2.0.54-3.src.rpm from a fedora mirror and rebuilt with
rpmbuild -ba SPECS/httpd.spec
But the rest are geniun updated fc3 packages .. so something is actually
doing that
I will dig into it, just running out of time today :)
Cheers
