Linux user auth and file permissions

[thepogoman]

I would like to create a PHP application that allows users to log in to a Linux box using their system username and password. After the user is logged in, the application needs to be able to read/write/execute files according to that user's file permissions.

Any suggestions?

I think youll want to take a look at the POSIX functions as they allow you to ghange user. But with the unix-passwd thing youll probably have to move to perl unless youve got crypt, but again perl might be better as you can unix PAM auth libraries.
