Running a script through webserver with priveleges

[Seather]

I need to run a certain script (shell or perl) through apache with php which should have permissions to do something as a complete different user, not root though.

Sudo is out of the question, and I don't exactly know how to code c wrappers.

Anyone that can give me some help on this?

Thanks

You're probably looking for suEXEC:
