Which group(s) should apache and x_ftp belong to by default?

[RadNadz]

I was working on an issue with apache not being able to run scripts and so I changed some user groups and turns out I removed something necessary. I'm not sure what I removed though.

I've been googling, but haven't seen an answer to this question.
