UID on APACHE ..

Hi Peoples, I have a BIG problem, In my WebServer, running Apache and PHP as Module, I have many diferents VirtualHost. Each VirtualHost running under a diferent user with suexec. But, the users call fails when they try to use functions to manipulate files/directories, I think this is happening because the PHP are calling the function as the general Apache user, and not the VirtualHost user .. I really appreciate if you have any clue to avoid this behavior ... Thanks. - Alexandre ...
