Adding System Level Accounts from chroot-ed Apache?

roadoi asks: "I have a Web server which is running RHLinux 6.0 and Apache 1.3.9+PHP 3.0.12 in a chrooted environment. This machine also runs an ftp server which authenticates off of the main /etc/passwd file. I want to have the ability to add system level accounts from the Web server (by running a script, etc.) and have accounts added to the main /etc/passwd file rather than the cut down /etc/passwd file lying within the chroot environment. Accounts should be active immediately so polling a database or the like at regular intervals is out of the question. Is this at all possible?" I see why polling some file would be such a bad idea, but maybe some kind of solution could be arranged where a daemon could be set to watch a port for account data. This opens up very large can of worms, however and is probably not the best option. Does anyone have any better solutions?
