When you use a program like Joomla or Mambo (and others) to add modules or componets, it uses apache to set these up on the server. Thus apache is set as the UID. Once that is done, you may want to change the UID for these files / folders.
If the server you are on has the latest version of DA, then you can use the filemanager to change the UID's. If the server is not running the latest version of DA, ssh to the server (if you have access) and change the UID of the directories and files to the correct user.
