Linux user creation with php

I am trying to write a php script to create users for my email server, however I am having an issue with the rights of the php intereter. The lines i am try to execute are as follows: 

useradd -m -s /usr/sbin/nologin username

and then user:pass | chpasswd.

Script on Linux is actually executed by apache itself. Apache’s user www-data needs to be granted privileges to execute certain applications using sudo.

There are ways to achive this,

You want to edit /etc/sudoers and using sudo visudo this can be done.

www-data ALL=NOPASSWD: /usr/sbin/useradd, usr/bin/php

Assuming that you want to run useradd and php using root privileges.

I see this same issue come up quite frequently. Apache runs as www-data:www-data on ubuntu. When you perform exec('useradd -m -s /usr/sbin/nologin username'), it will execute with the same permissions as www-data has, not as a sudoer in the command line.

You need to adjust the permissions, fix the relationship, or offload it to a Cron Task that can execute with the correct permissions.
